Mini-Lesson

Review mixed-operation problems (first taught Week 16). 'A lemonade stand had 45 cups. They sold 28 cups, then a neighbor brought 20 more cups. How many cups now?' Think aloud: 'First something leaves, then something comes.' Write 45 - 28 = 17, then 17 + 20 = 37. Show how to check the first step backward: 17 + 28 = 45, yes.

Your child solves four problems and writes a check for each: 'A library had 72 picture books, lent 35, and got 18 back. How many on the shelf?' (55). 'Kai saved 56 cents, spent 29 cents, then earned 40 cents. How much now?' (67 cents). 'A parking lot had 38 cars; 16 left and 27 arrived. How many cars?' (49). 'Tom had 90 blocks, used 47 for a tower, and then found 15 more. How many not in the tower?' (58).

Shared Reading

Read 'Cookies' from Frog and Toad Together, then read A Sick Day for Amos McGee by Philip C. Stead. For the second book, cover the words with a sticky note on three pages and ask your child to tell what is happening from the picture alone, then uncover and check.

Mini-Lesson

Say: 'In Week 5 we learned that pictures tell things the words leave out.' Look at the page in Amos McGee where the animals ride the bus. Ask: 'What do the words say? What does the picture add?' List two picture-only details (the red balloon, the animals' faces) on the whiteboard.

15 min

Guided Reading

Your child chooses one page from each book and completes a two-box page in the reading notebook: 'The words tell me' and 'The picture tells me'. Then ask: 'How do the pictures in Cookies show that Frog and Toad have no will power?'

Writing Workshop

Genre review, day three: informational (first taught in Week 7). Your child writes a four-sentence 'All About Friendship' paragraph with a topic sentence, two facts about what friends do (use examples from Amos and the animals), and a closing sentence.

10 min

Word Study

Prefix and suffix review from Weeks 5 and 7. Build words with cards: un + kind, re + read, pre + heat, care + ful, help + less, quick + ly. Your child reads each whole word and gives a one-sentence meaning ('unkind means not kind').

Review

Check the bean bag together. Your child draws what the beans look like today in the Bean Diary (usually a swollen seed coat, sometimes a tiny white root tip by day 3). Ask: 'Which stage of the cycle is this?'

20 min

Deeper Investigation

Draw three big circles on one sheet. In circle 1 your child draws and labels the frog cycle (egg, tadpole, tadpole with legs, frog), in circle 2 the butterfly cycle (egg, caterpillar, chrysalis, butterfly), and in circle 3 the bean cycle from Monday. Use a library book such as From Tadpole to Frog by Wendy Pfeffer or a Let's-Read-and-Find-Out title for reference. Then ask your child to circle the stage in each cycle where the living thing looks most different from the adult.

Data Discussion

Ask: 'What do all three cycles have in common?' Guide toward: every one starts with an egg or seed, every one grows and changes, and every adult makes new eggs or seeds. Write the shared pattern as one sentence at the bottom of the page.

Today's Practice

One page for your child for each lesson. Answers are for grown-ups.

Math practice · Week 31 · Wednesday

I can solve problems that add and subtract, then check my answer.

Look: 61 marbles, 25 go, 14 come

First something leaves: 61 − 25 = 36.
Then something comes: 36 + 14 = 50.
Check step 1 backward: 36 + 25 = 61. Yes!

Solve in two steps. Check the first step with the opposite operation.

A pond had 53 ducks. 27 flew away, then 18 landed. How many ducks now?
Maya had 80 cents. She spent 45 cents, then earned 25 cents. How much now?
A shelf had 64 jars. 29 were sold, then 30 more came. How many jars now?
Theo had 37 marbles. He won 24 more, then gave 19 to a friend. How many now?
