Lesson 4 Pattern Block Puzzles and Equations

- Let’s use equations to show how many of each shape there are.

Warm-up Which One Doesn’t Belong: Equations

Which one doesn’t belong?

$3 + 3 = 6$
$6 = 4 + 2$
$4 + 3 = 7$
$4 + 2 = 6$

Activity 1 Match Equations to Pattern Block Puzzles

$8 = 4 + 4$
$6 + 1 = 7$

$10 = 2 + 8$
$7 = 6 + 1$

$2 + 3 = 5$
$9 = 6 + 3$

Activity 2 Make Shapes to Represent Equations

Put together pattern blocks to make a shape that matches each equation. Trace or draw each shape that you make.

$4 = 1 + 3$
$10 + 0 = 10$
$5 + 4 = 9$
$8 = 2 + 6$
$3 + 3 = 6$
$7 = 2 + 5$
