Lesson 18 Concept Development and Problem Set
Sam brought 8 pieces of fruit at the farmer’s market. He loves apples and oranges, so he bought some of each. Draw a plate and show his fruit on the plate. Don’t lose any!
Show your work to your friend. Does her plate look the same? Can you make a number bond and number sentence about your picture?
Devin has 6 Spiderman pencils. He put some in his desk and the rest in his pencil box. Write a number sentence to show how many pencils Devin might have in his desk and pencil box.
Shania made 7 necklaces. She wore some of the necklaces and put the rest in her jewelry box. Use the linking cubes to help you think about how many necklaces Shania might have on and how many are in her jewelry box. Then, complete the number sentences.
Tommy planted 8 flowers. He planted some in his garden and some in flowerpots. Draw how Tommy may have planted the flowers. Fill in the number sentences to match your picture.
Create your own story and draw a picture. Fill in the number sentences. Tell your story to a friend.
1. Talk about the pencils on your paper. Did you and your neighbor put the same amount in the desk and the pencil box?
2. How did the cubes help you to think about Shania’s necklaces?
3. What was the difference between the two types of number sentences we made for each picture on the board?
4. When we were drawing our jellybean number sentences, did it matter which color we wrote about first?
5. Could different pictures about the 8 jelly beans still be true? Why?
6. Let’s put our muddy ball number sentences and pictures in order. I’ll put the first ones, 7 = 1 + 6. Next comes 7 = 2 + 5 (move the cards). Talk to your partner, which number sentence will come next in our pattern?
7. Talk to your partner. What patterns do you notice?
8. What was the same about all of our problems today? (There was more than one way to solve and write the problem.)
