Summary

+
+
= 18

b) There are equal groups with 7 coins in each group.
+
+
+
+
= 20

Add equal groups:
To solve, ensure the number of items in each group is the same. In these cases, it's 3 or 7. Then, simply add the numbers of groups together.

2. Number Sentence for Rosie's Coins:
Rosie has 20p. She could have:
- 4 x 10p coins
- 8 x 5p coins
- 16 x 2p coins

3. Pictures to Represent:
a) 8 + 8 = 16: Draw two groups of 8 objects, e.g., 8 apples and 8 oranges.
b) 2 + 2 + 2 = 6: Illustrate three groups with 2 items in each.

4. Dexter's Coins:
a) Dexter has five 1p coins (5 x 1p = 5p).
b) Dexter has five 2p coins (5 x 2p = 10p).
c) Dexter has five 5p coins (5 x 5p = 25p).
d) Dexter has five 10p coins (not possible with only 1p, 2p, 5p, and 10p coins).

5. Complete the Sentences:
a) 3 + 3 + 3 + 3 = 12: Four groups of 3 items each.
b) 2 + 2 + 2 + 2 + 2 + 2 + 2 = 14: Seven groups with 2 items, or one group with 7 items.

Description

a) There are 6 equal groups with 3 coins in each group.
b) There are 7 equal groups with 2 coins in each group.

a) **Number Sentence:** 8 + 8 = 16
* **Picture:** Two rows of eight objects, representing two sets of 8 added together.

b) **Number Sentence:** 2 + 2 + 2 = 6
* **Picture:** Three circles, each containing two objects, symbolizing the addition of three groups of two.

a) Dexter has five 5p coins. (Most appropriate as 1p, 2p, and 10p coins would total less than 5p.)

a) 3 + 3 + 3 + 3
