Unit openers
Big idea
Your child measures real objects with rulers, yardsticks and tape measures, in inches and centimeters, and learns to estimate first. Then they solve length problems, add and subtract on number lines, tell time to the nearest 5 minutes and count coins and bills. This is math your child will use every day.
Why it matters
It puts the adding and subtracting from Units 2 and 3 to work with real units. The measurements feed straight into the line plots and graphs of Unit 5.
Standards in plain language
- 2.MD.A.1 Chooses the right measuring tool and measures from zero.
- 2.MD.A.2 Measures in inches and in centimeters and explains why the numbers differ.
- 2.MD.A.3 Makes a sensible estimate of a length before measuring.
- 2.MD.A.4 Measures two objects and says how much longer one is.
- 2.MD.B.5 Solves word problems about length.
- 2.MD.B.6 Uses a number line to show and solve addition and subtraction.
- 2.MD.C.7 Tells time to the nearest 5 minutes on analog and digital clocks and uses a.m. and p.m.
- 2.MD.C.8 Knows coin values, counts mixed coins and solves money word problems.
Mastery looks like
- Measures an object starting at 0 and picks a sensible tool (a ruler for a spoon, a tape measure for a doorway).
- Measures the same object in inches and centimeters and explains why the centimeter number is bigger.
- Solves a length story like 'A rope is 80 feet. 34 feet are cut off.' with a drawing and an equation.
- Reads an analog clock to the nearest 5 minutes, writes the time digitally and uses a.m. and p.m.
- Counts mixed coins starting with the largest value and figures change from a quarter or a few dollars.
Vocabulary
length, ruler, yardstick, inch, centimeter, estimate, equation, number line, jump, analog, digital, minute, coin, dollar
Materials
- 12-inch ruler with a centimeter side
- Yardstick or a 36-inch strip of masking tape
- Tape measure
- Paper plate clock with cardstock hands
- Real coins (a coin jar) and a few dollar bills
- String, ribbon and scissors
Short-week pacing
Keep the hands-on Monday lesson and the Friday check. The Thursday project (the frame, the shelf, the paper chain, the pretend store) is the easiest to drop; ask its main question during Friday's warm-up instead.
Watch across the unit
Across length, time and money, children misread the tool: starting a ruler at 1 or at the end of the wood, mixing up the hour and minute hands, or thinking a dime is worth less than a nickel because it is smaller. Have your child say the rule aloud: start at 0, the short hand is the hour, size does not tell value.
Big idea
Your child collects real data, such as the lengths of kitchen spoons or family votes, and shows it on line plots, picture graphs and bar graphs. Then the unit turns to shapes: naming them by their sides and corners, splitting rectangles into rows and columns of squares, and sharing shapes fairly in halves, thirds and fourths.
Why it matters
It uses the measuring from Unit 4 and the arrays from Unit 3. Equal shares are the first step toward fractions in third grade.
Standards in plain language
- 2.MD.D.9 Measures several things and shows the data on a line plot.
- 2.MD.D.10 Makes and reads picture graphs and bar graphs and answers questions about them.
- 2.G.A.1 Names and draws shapes by their attributes, such as number of sides and angles.
- 2.G.A.2 Splits a rectangle into rows and columns of equal squares and counts them.
- 2.G.A.3 Splits shapes into 2, 3 or 4 equal parts and uses the words halves, thirds and fourths.
Mastery looks like
- Measures objects, builds a line plot with a title and unit, and says which length is most common.
- Makes a picture graph and a bar graph from survey data and answers how-many-more questions from them.
- Names triangles, quadrilaterals, pentagons and hexagons by counting sides and vertices, even when stretched or tilted, and knows a cube has 6 faces.
- Splits a rectangle into rows and columns of equal squares and writes a repeated addition sentence for the total.
- Cuts circles and rectangles into halves, thirds and fourths and explains why one third is bigger than one fourth of the same whole.
Vocabulary
line plot, data, picture graph, bar graph, compare, attribute, vertex, quadrilateral, partition, row, column, half, third, fourth, equal share, graph, shape
Materials
- Ruler
- Grid paper
- Toothpicks or straws for building shapes
- Square crackers or sticky notes
- Paper plates, paper circles and scissors
- A die or blocks to count faces
Short-week pacing
Keep Monday's data collecting or shape building and the Friday check. The Thursday real-life task (hand spans, brownie pans, sharing food) is the easiest to drop; its main question can be a one-question Friday warm-up.
Watch across the unit
The most common misconception is that a bigger number means a bigger piece: many children think one fourth is bigger than one third because 4 is bigger than 3. Cut two same-size strips into thirds and fourths and lay the pieces side by side.
Big idea
Your child takes on harder books, both detailed nonfiction like A Drop of Water and the chapter book Charlotte's Web, using fix-it moves when a text gets tricky. In writing, your child revises and edits a piece, types and publishes it with a photo, and works on grammar such as irregular plurals, reflexive pronouns, adjectives and adverbs.
Why it matters
It asks your child to use the question, main-topic and retelling skills of Units 1 to 3 on longer texts with less help. Revising and publishing return in the Author's Celebration at the end of the year.
Standards in plain language
- RI.2.10 Reads and understands grade-level nonfiction, with some help on the hardest texts.
- RL.2.10 Reads and understands grade-level stories and poems, with a little help on the hardest.
- W.2.5 Goes back to a piece of writing to add details and fix mistakes, with help.
- W.2.6 Types a short piece on a computer or tablet and shares it, with help.
- RF.2.3 Uses phonics to sound out new words, including vowel teams, prefixes, suffixes and longer words.
- RF.2.4 Reads smoothly, at a good pace, with expression and understanding.
- L.2.1 Uses correct grammar: collective nouns, irregular plurals, reflexive pronouns, past tense, adjectives and adverbs.
- L.2.2 Uses capitals, commas, apostrophes and correct spelling.
- L.2.4 Works out unknown words with context clues, word parts and dictionaries.
- L.2.6 Uses new words from books and conversations when talking and writing.
Mastery looks like
- Uses rereading, the pictures and word parts to make sense of a hard sentence in a nonfiction book.
- Asks thick and thin questions and answers them starting with 'The book says...'
- Retells a story with the five-finger retell and names its central message.
- Revises by adding, removing, moving or swapping words (ARMS) and edits for capitals, usage, punctuation and spelling (CUPS).
- Uses collective nouns, irregular plurals (feet, mice), reflexive pronouns and words collected from reading in their own writing.
Vocabulary
revise, self-correct, collective noun, plural, retell, reflexive, linking word, response, lesson
Materials

- The Stories Julian Tells by Ann Cameron
Short-week pacing
Keep the read-aloud, since Charlotte's Web runs from Week 22 into the next unit and each chapter depends on the last. Merge two writing days, and let independent reading double as the Friday reading response.
Watch across the unit
With harder texts, children often keep reading after the meaning breaks down or guess a word from its first letter. Teach the question 'Does that make sense?' and praise every self-correction by name.
Big idea
This unit is about talking about books: following conversation rules, taking roles, building on someone else's idea and asking for clarification. Your child reads books linked to science and social studies, writes a true recount and a short research paragraph, and plays with shades of meaning like warm, hot and scorching.
Why it matters
It builds on the speaking and presenting of Unit 3 and the research skills of Unit 2. The conversation habits and recordings are used again in the Unit 6 showcase and Author's Celebration.
Standards in plain language
- SL.2.1 Takes part in real conversations: listening, taking turns, staying on topic and asking questions.
- SL.2.2 Tells the main ideas and details of something heard.
- SL.2.3 Asks a good question after listening to someone.
- SL.2.4 Tells a story or event clearly, in order, loudly enough and with good details.
- SL.2.5 Records a reading and adds pictures to make a story clearer.
- SL.2.6 Answers in full sentences when it matters.
- RL.2.1 Answers who, what, where, when, why and how questions about a story.
- RL.2.2 Retells a story in order and explains its lesson.
- RL.2.3 Explains what characters do and feel when big things happen.
- RL.2.4 Notices how rhyme, repeated lines and beat give a poem or story its sound and meaning.

- RL.2.6 Knows characters have different points of view and uses different voices for them.
- RL.2.7 Uses both the pictures and the words to understand a story.
- W.2.3 Writes stories in order with details, time words and an ending.
- L.2.1 Uses correct grammar: collective nouns, irregular plurals, reflexive pronouns, past tense, adjectives and adverbs.
- L.2.4 Works out unknown words with context clues, word parts and dictionaries.
- L.2.5 Connects words to real life and notices shades of meaning (mad, angry, furious).
Mastery looks like
- Follows the talk rules (eyes on the speaker, one voice at a time, stay on topic) and builds on an idea with 'I want to add on...'
- Asks a clarifying question, such as 'What do you mean by...?', when something is unclear.
- Explains what the pictures add to the words and describes a story's beginning, middle and end.
- Writes a recount of a real event with time words, a line of dialogue and a clear ending.
- Orders words by strength (sad, upset, furious) and chooses the one that fits.
Vocabulary
conversation, role, build on, point of view, purpose, structure
Materials
- Talking Together chart on large paper
- Speaker, Listener and Questioner role cards
- Sticky notes
- Phone for recording
- Research notebook
- Index cards for word sets

- The Day the Crayons Quit by Drew Daywalt
- Ox-Cart Man by Donald Hall
Short-week pacing
Keep the conversations, since talking is the skill being taught; a 5-minute stem conversation can replace a written response. Drop one phonics review day and one independent reading block, and keep the Friday conversation, retelling or reading check.
Watch across the unit
In conversation, children often wait for their turn and then share their own idea without connecting it to what was just said. Ask for a stem at the start of each turn, such as 'I agree because...' or 'I want to add on...'
Big idea
Your child explores how water, ice and wind shape the land. With a pan of sand and water, a globe toss, a gravel 'glacier' and homemade wind tools, your child sees that some changes to Earth happen fast and others take thousands of years, and learns to show land and water on a map.
Why it matters
It builds on the melting and freezing of Unit 1 and the testing habits of Unit 3. Mapping connects to the Unit 2 social studies maps, and changing land leads into the habitats of Unit 5.
Standards in plain language
- 2-ESS1-1 Gives examples of Earth changes that happen fast and ones that happen slowly.
- 2-ESS2-1 Understands erosion and compares ways people slow it, like planting grass.
- 2-ESS2-2 Makes a model showing landforms and bodies of water.
- 2-ESS2-3 Says where water is found on Earth and that it can be liquid or frozen solid.
Mastery looks like
- Explains that most of Earth's surface is covered by water, and that water flows downhill and collects in low places.
- Tells weathering (breaking rock into smaller pieces) from erosion (moving the pieces) and explains how plants slow erosion.
- Sorts Earth changes into fast (a landslide, a flood) and slow (a canyon forming, a pebble wearing smooth).
- Draws a map from above with a key and finds rivers, lakes and mountains on a real map.
- Lists where water is found as a liquid and as a solid (glaciers, ice caps, snow).
Vocabulary
landform, mountain, river, lake, ocean, weathering, erosion, map, key, symbol, glacier, ice cap, solid, liquid, wind
Materials
- Baking pan, sand or soil, and a cup with holes for 'rain'
- Globe or world map
- Ice cubes, gravel and paper cups
- Sugar cubes in a jar with a lid
- Paper cup, crepe paper or plastic strips, and string for a wind sock
- Paper plates
- Science notebook
Short-week pacing
Keep Monday's model or investigation and a short Friday 'I learned' conclusion. Trim the Friday art or walk first, and in Week 23 keep the weather log going for two minutes a day even on skipped days.
Watch across the unit
Children often think the land never changes, or that every change is sudden. The sugar cube shake and the planted and bare slopes show how small, steady forces add up over a very long time.
Big idea
Your child counts the kinds of living things in a small square of ground, sorts animals into groups by features they can see, and tests again that plants need sun and water. The unit then traces how living things depend on each other through pollination and food webs, how people can protect habitats, and how features like beaks and blubber help animals survive where they live.
Why it matters
It deepens the plants, animals and habitats of Unit 2 and reuses the Unit 3 design steps to protect a model pond. It leads into the life cycles and review of Unit 6.
Standards in plain language
Mastery looks like
- Surveys two small areas, compares how many kinds of living things each has, and explains why (shade, water, plants, hiding places).
- Sorts animals into mammals, birds, reptiles, amphibians, fish and insects by a visible feature, and knows a spider is not an insect.
- Builds a food chain that starts with the sun and a plant, and predicts what happens to a food web when one living thing is removed.
- Gives two examples of plants and animals depending on each other, such as a bee and a flower.
- Names an adaptation, like a hooked beak or blubber, and explains how it helps an animal survive.
Vocabulary
biodiversity, classification, mammal, bird, reptile, amphibian, fish, insect, interdependence, habitat, food chain, food web, ecosystem, producer, consumer, adaptation
Materials
- String or a hula hoop to mark a square
- Animal cards (magazine cutouts, printouts or sketches)
- Clear cups, paper towels and dried beans
- Shoebox lid or baking pan for a model pond
- Index cards and yarn for a food web
- Tweezers, clothespin, slotted spoon and straw for the beak test
- Science notebook
Anchor books
- Who Eats What? Food Chains and Food Webs by Patricia Lauber
Short-week pacing
Keep Monday's investigation and a short Friday conclusion. Keep living setups like the bean cups going with a quick daily check, and skip the art connection when time is short.
Watch across the unit
Children often sort animals by how they move or where they live ('a penguin can't fly, so it isn't a bird'; 'a spider is a bug, so it's an insect'). Bring them back to the feature rule: feathers make a bird, six legs make an insect.
