Activities

Warm-Up

Build two towers of blocks, 9 tall and 6 tall, side by side. Ask, 'How many more blocks in the tall tower?' Line them up and point to the extra 3. Repeat with 12 and 7. Say, 'Comparing means lining them up and looking at the difference.'

15 min

Mini-Lesson

Read: 'Carlos has 34 books. Ana has 21 books. How many more books does Carlos have than Ana?' Draw two bars stacked, the top bar longer and labeled 34, the bottom bar shorter labeled 21, with a ? bracket over the extra length. Write 34 - 21 = ? (13). Then reword it: 'How many fewer books does Ana have?' and show it is the same model and same answer. Name this a 'compare' problem.

15 min

Practice

Your child solves: 'The oak tree is 48 feet tall. The maple tree is 29 feet tall. How much taller is the oak?' (19) and 'Grace scored 15 points. Wes scored 7 fewer than Grace. How many points did Wes score?' (15 - 7 = 8, note that fewer here means Wes's bar is shorter). Draw both comparison bars for each and label the ?.

5 min

Wrap-Up

Ask, 'How is a compare bar model different from a take-from bar model?' Listen for 'two bars instead of one' and 'nothing gets crossed out.'

Read-Aloud

Read 'Yeh-Shen: A Cinderella Story from China' by Ai-Ling Louie. Before starting, say that this version is more than a thousand years older than the French one. Stop at the fish bones and ask: 'Who is the helper in this story? Who was the helper in Marcia Brown's?'

10 min

Mini-Lesson

Draw a large Venn diagram with two overlapping circles labeled Cinderella (France) and Yeh-Shen (China). Model one entry for each part: only France has a pumpkin coach, only China has a magic fish, both have a lost slipper. Explain that the middle is for things both stories share.

Guided Reading

Flip between the two books with your child to hunt for four more Venn entries: the mean stepfamily (both), a festival instead of a ball (Yeh-Shen), the tiny golden slipper (Yeh-Shen), the fairy godmother (Cinderella). Your child writes each entry in the right spot. Support: you write, they say where it goes. Stretch: they add how each story's helper first appears.

Writing Workshop

Turn the Venn diagram into sentences. Your child writes one 'Both stories' sentence and one 'But' sentence: 'Both stories have a girl who loses a slipper. But in Yeh-Shen a fish helps her, and in Cinderella a fairy godmother helps her.'

Phonics: Contractions

Teach that a contraction squeezes two words together and the apostrophe marks where letters left. Write and read the 'not' family: is not / isn't, cannot / can't, do not / don't, did not / didn't, was not / wasn't, are not / aren't, will not / won't, could not / couldn't. Your child covers the long form and reads the short one, then reverses.

Science

Students will gather information about a problem by interviewing people and testing the situation, then list the criteria a good solution must meet (K-2-ETS1-1).

Review

Read the problem statement on the notebook cover. Ask: 'How would we know if a solution worked? What must it do?' Introduce the word 'criteria': the things a solution must do to count as a success.

20 min

Deeper Investigation

Interview two family members (in person or by phone) with three questions: 'Do crayons roll away from you? What would help? What must the fix NOT do?' Write short answers in the notebook. Then run a fair test of the roll: tilt a book slightly with a pencil under one end, release a crayon from the top, and measure with a ruler how far it rolls; repeat three times and write the distances.

Data Discussion

Write a criteria list of three items, for example: 'Holds at least 8 crayons. Stops rolling on a tilted table. Fits in a pencil box.' Add one constraint: 'Made only from things in the recycling bin.' Support: offer two criteria and have your child choose one to add. Stretch: have your child rank the criteria from most to least important and explain the order.

Math practice · Week 14 · Wednesday

I can solve a compare story with two bars.

Look: Ava has 43 cards. Ben has 28 cards. How many more does Ava have?

Draw two bars. Ava's bar is longer.
Put a ? over the extra part of Ava's bar.
43 − 28 = 15. Ava has 15 more. Ben has 15 fewer.

Draw two bars. Mark the ?. Write the equation and solve.

Owen has 56 marbles. Ria has 32 marbles. How many more marbles does Owen have?
A pine tree is 45 feet tall. A birch tree is 27 feet tall. How much taller is the pine tree?
Dev scored 18 points. Mia scored 9 fewer than Dev. How many points did Mia score?
The red jar has 71 beans. The blue jar has 46 beans. How many fewer beans are in the blue jar?
