Understanding Equal Groups and Multiples
Equal Groups
Sets with the same number of items (e.g., 
shoe pairs = groups of 2, egg cartons = 
groups of 6 or 12).
Multiples
Numbers from multiplying by 1, 2, 3, etc.
Multiplication
Counts equal groups (like jumps).
Division
Shares equally or finds group counts. 
Useful for counting and fair sharing.

Animal Jumps
Freddy the Frog
Jumps 3 steps.
Multiples: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...
Will Freddy land on 67? No, 67 ÷ 3 has a 
remainder.
Squeaky the Squirrel
Jumps 4 steps.
Multiples: 0, 4, 8, 12, 16, 20, 24, 28, 32, 36, 
40, ... 60.
Jumps to 60: 60 ÷ 4 = 15 jumps.

Rosie the Rabbit
Jumps 6 steps.
Multiples: 0, 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, ...
Smallest 3-digit number: 6 × 17 = 102 (6 × 16 = 96 is 2-
digit).
Jumps to 102: 17 jumps.
Kevin the Kangaroo
Jumps 8 steps.
Multiples: 0, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, ...
