Lesson 5 Story Problems about Shapes

- Let’s solve story problems and match them to equations.

Warm-up Notice and Wonder: Questionless Story Problem

What do you notice?
What do you wonder?

Elena used 9 pattern blocks to make a train.
Then she took 3 of the pattern blocks off of the train and put them back in the bucket.

Activity 1 Match Story Problems to Equations

Clare made a shape with 7 pattern blocks.
Her little brother came and took 3 of the pattern blocks.
How many pattern blocks does Clare have now?
1. $7 = 4 + 3$
2. $7 - 3 = 4$
3. $7 + 3 = 10$
Kiran put together 2 pattern blocks to make a shape.
Jada placed 5 more pattern blocks on the shape.
How many pattern blocks are in Kiran and Jada’s shape?
1. $5 - 2 = 3$
2. $4 = 2 + 2$
3. $2 + 5 = 7$

Activity 2 Solve Story Problems

Andre put together 4 pattern blocks to make a shape.
Then Andre put 4 more pattern blocks on the shape.
How many pattern blocks are in Andre’s shape?
equation:
pattern blocks.
$8 =$ $+$
Elena used 9 pattern blocks to make a train.
Then she took 3 of the pattern blocks off of the train and put them back in the bucket.
How many pattern blocks are in Elena’s train now?
equation:
pattern blocks.
$9 - 3 =$
