Quarter 2 · Detailed day-by-day lesson plans · Days 81–85
0 of 15 lessons done this week
Week 17 identifies odd and even numbers by pairing, by looking at the ones digit, and by writing even numbers as two equal addends. In reading, children compare important points across two texts and record stories on audio.
Pair up socks from the laundry to see odd vs. even at home.
Counters, two short nonfiction articles, recording app

Students will determine whether a group of up to 20 objects is odd or even by pairing objects (2.OA.C.3).
3 quick questions from earlier weeks · about 3 minutes
Warm-Up
Spiral from Week 16: solve 'Kai had 24 beans, gave 9 away, then found 7. How many now?' (22). Then hand your child those 22 beans and say, 'Can you split these into two equal teams with none left over?' Let them try before naming odd or even.
Mini-Lesson
Take 8 beans and pair them up in two rows of 4: 'Every bean has a partner, so 8 is even.' Take 9 beans and pair them: one is left alone, so 9 is odd. Repeat with 12 (even) and 15 (odd). Write each number with 'E' or 'O' on a chart from 1 to 20 as you go, filling in only the ones you test today.
Practice
Your child grabs a handful of beans (up to 20), counts, pairs them, and records the number and odd or even on the chart. Do this 8 times. Then check the socks in a drawer, the shoes by the door, and the chairs at the table, pairing each set and recording.
Wrap-Up
Ask, 'What does an odd number always have when you pair up?' Listen for 'one left over.' Add odd and even to the word wall.
Students will identify the most important points in a nonfiction text and use prefixes to determine word meaning (RI.2.2, RI.2.9, L.2.4b).
3 quick questions from earlier weeks · about 3 minutes
Read-Aloud
Read 'Owls' by Gail Gibbons. Say that last week they judged reasons; this week they will find the most important points two authors make about the same animal. Stop after each spread and ask: 'If you could keep one fact from this page, which one?'
Mini-Lesson
Explain that an important point is something the whole book keeps coming back to, not a small detail. Start an Important Points chart with two columns, Gail Gibbons and National Geographic, and write three points from Gibbons (owls hunt at night; they have special feathers for silent flight; they swallow prey whole and cough up pellets).
Guided Reading
Reread the pages on owl eyes and ears with your child reading the labels. Ask them to say which sentence on each page is the main idea and which are details. Add one more important point to the chart.
Writing Workshop
Introduce this week's project: an audio recording of a short piece your child writes. Today they write a four-sentence Owl Fact Report from the Gibbons book with a topic sentence, two facts, and a closing. Keep it in the Writing Folder.
Phonics: Prefixes
Teach un- (not) and re- (again). Write and read: unhappy, unlock, untie, unfair, unsafe, redo, refill, replay, rewrite, reheat. Your child covers the prefix, reads the base word, then uncovers it and says the new meaning ('lock, unlock, not locked').
Students will build a second, different solution to the same problem so that two designs can be compared fairly (K-2-ETS1-3).
Science Question of the Week
Ask: 'How can we tell which of two designs is better?' Look at the two runner-up sketches from Week 15 and pick the one most different from the finished holder (if the winner was a box, choose a tube or a tray).
Investigation
Build Design B from the runner-up sketch in 15 minutes using the same kinds of materials. Keep a star tally of changes on the plan just as before. Set Design A and Design B side by side and write on an index card under each: its name, its main material, and one way it is different from the other.
Wrap-Up
Ask: 'To compare fairly, what has to be the same in both tests?' (same crayons, same tilt, same table). Write 'Fair test: same crayons, same book, same table' at the top of Wednesday's page.
Read it aloud first while your child follows along. Then read it together, and let your child read the parts they can. Talk about the words in the word box.
A town sits on one side of a wide river. People need to get to the other side. Engineers came up with two solutions. Read about each one.
A bridge lets people cross at any time of day or night. Cars, bikes and people on foot can all use it. But a bridge costs a lot of money. It can take years to build.
A ferry is a boat that carries people and cars across water. A ferry can start working soon, and it costs less than a bridge. But a ferry runs only at certain times. People have to wait for it. In a bad storm, it may not run at all.
Both solutions help people cross the river. Each one has good points and problems. Engineers compare solutions like these to choose the best one for a town. Which would you choose? Why?

Kim built two boats from foil. She tested them in the same tub of water. Boat A held 12 pennies before it sank. Boat B held 20 pennies. Boat A was easier to fold.

Testing two designs the same fair way
Try it (10 min): Go on an odd and even hunt. Count the forks in the drawer, the chairs at the table and the buttons on a coat. Pair each set up to check.
Talk about it: How can you tell a number is even without pairing?
Try it (10 min): Read two short pieces about the same animal, like a library book and a magazine page. Each person says one point both pieces make.
Talk about it: If two authors say the same thing, why might it be important?
Try it (10 min): Fold two paper airplanes in different ways. Throw each one three times from the same spot and measure with steps. Which flew farther?
Talk about it: What did you keep the same so the test was fair?
Try it (10 min): Look at a calendar together. Find three national holidays and mark each with a small drawing.
Talk about it: Which holiday does our family celebrate, and how?
We did blank of 4 activities.
