Warm-Up

Spiral from Week 9: solve 356 + 428 with a drawing (784). Then on the hundreds chart, put a bean on 47 and slide it down one row to 57 and up one row to 37. Ask what changed and what stayed the same (tens digit changed, ones digit stayed).

Mini-Lesson

Write 346 on an index card with each digit on its own card: 3, 4, 6. Say, 'Ten more means one more stick.' Swap the 4 for a 5: 356. Ten less: swap for a 3: 336. Then the tricky case, 396 + 10: 9 tens plus 1 ten is 10 tens, which regroups to a hundred, so 406. Show it with straw bundles.

Practice

Say each number and your child answers 10 more and 10 less aloud: 234, 571, 809, 450, 693, 385, 902, 197 (answers 244 and 224, 581 and 561, 819 and 799, 460 and 440, 703 and 683, 395 and 375, 912 and 892, 207 and 187). They write only the ones they hesitate on.

Read-Aloud

Say, 'Last week you used headings and captions to find facts. This week we ask a bigger question: why did the author write this book at all?' Read the first half of 'Monarch Butterfly' by Gail Gibbons, through the caterpillar stage. Pause twice to ask, 'What is Gail Gibbons trying to explain on this page?'

10 min

Mini-Lesson

Make an anchor chart with three purposes and a picture for each: to answer a question, to explain how something works, to describe what something is like. Write 'Monarch Butterfly' under 'explain' and have your child say why ('It explains how a caterpillar turns into a butterfly').

Guided Reading

Reread the milkweed pages together. Ask, 'What does the author want me to know about milkweed?' and have your child find the sentence that shows it. This links to science this week, where you are learning that animals depend on plants; a monarch cannot live without milkweed.

Writing Workshop

Launch the research project: an 'All About' book on a plant or animal connected to the science unit. Offer choices (bean plant, sunflower, monarch butterfly, honeybee, ant, earthworm) and have your child pick one and write three questions they want to answer ('What does it eat? Where does it live? How does it grow?'). Set up a research folder with one page per question.

10 min

Word Study

Teach that a base word is the root you can build on. Write these word families and have your child circle the base in each: play, replay, playful; help, helper, helpless; read, reread, reader; care, careful, careless. Then your child builds one new word from the base 'hope' and tells what it means.

Science Question of the Week

Say, 'Last week you built a habitat. Every animal in it needed plants somehow. Our question this week: How do animals depend on plants, and how do plants use animals to move their seeds?'

Investigation: What Did I Eat From a Plant?

Set out breakfast and lunch items: bread, an apple, peanut butter, cheese, a carrot, cereal. Your child sorts them into From a Plant, From an Animal, and Both, then traces the animal foods back: 'Cheese comes from a cow, and the cow eats grass.' Then walk outside and rub a fuzzy sock or an old mitten across weeds and tall grass; look for seeds that stick, and count them.

Today's Practice

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

Math practice · Week 10 · Monday

I can find 10 more and 10 less in my head.

Look: 523

10 more: the tens digit goes up by 1. 523 → 533.
10 less: the tens digit goes down by 1. 523 → 513.
If the tens digit is 9, 10 more makes a new hundred: 491 → 501.

Write 10 less and 10 more. Circle the digit that changed.

10 less ____ 128 10 more ____
10 less ____ 462 10 more ____
10 less ____ 715 10 more ____

I can tell what an author wants to explain.

Look: Why did the author write it?

Read: First, mix flour and water. Next, add salt.
The author tells the steps to make something.
So the author wrote it to explain.

How a Chick Hatches

A hen sits on her eggs to keep them warm. After about three weeks, the chick inside is ready. It pecks a small hole in the shell with a tiny tip on its beak. Then it pushes and wiggles until the shell cracks open. The wet chick rests. Soon its feathers dry and get fluffy.

A wet baby chick pushes its way out of a cracked egg.

Use the page above.

Underline the sentence that tells how the chick makes the first hole.
What does the author want you to know?
