How many groups are there? Tell a story about the groups. 2. Complete drawings and multiplication and division sums of the following.

Here are the solutions for the grouping problems: 1. How many groups are there? First image (green blocks, 4 rows of 3): Groups: 4 Addition sum: 3 + 3 + 3 + 3 = 12 Multiplication sum: 4 × 3 = 12 Division sum: 12 ÷ 4 = 3 Second image (green blocks, 3 rows of 4): Groups: 3 Addition sum: 4 + 4 + 4 = 12 Multiplication sum: 3 × 4 = 12 Division sum: 12 ÷ 3 = 4 Third image (long green blocks, 5 rows of 10): Groups: 5 Addition sum: 10 + 10 + 10 + 10 + 10 = 50 Multiplication sum: 5 × 10 = 50 Division sum: 50 ÷ 5 = 10 Fourth image (red squares, 3 groups of 2): Groups: 3 Addition sum: 2 + 2 + 2 = 6 Multiplication sum: 3 × 2 = 6 Division sum: 6 ÷ 3 = 2 2. Complete drawings and multiplication and division sums of the following: 4 groups of 2 each: Drawing: Draw 4 separate groups, with 2 items in each group (e.g., || || || ||). Multiplication sum: 4 × 2 = 8 Division sum: 8 ÷ 4 = 2 5 groups of 2 each: Drawing: Draw 5 separate groups, with 2 items in each group (e.g., || || || || ||). Multiplication sum: 5 × 2 = 10 Division sum: 10 ÷ 5 = 2 4 groups of 10 each: Drawing: Draw 4 separate groups, with 10 items in each group. Multiplication sum: 4 × 10 = 40 Division sum: 40 ÷ 4 = 10 2 groups of 100 each: Drawing: Draw 2 separate groups, with 100 items in each group. Multiplication sum: 2 × 100 = 200 Division sum: 200 ÷ 2 = 100 6 groups of 100 each: Drawing: Draw 6 separate groups, with 100 items in each group. Multiplication sum: 6 × 100 = 600 Division sum: 600 ÷ 6 = 100 Division sums for "shared between" problems: 8 shared between 4: Division sum: 8 ÷ 4 = 2 10 shared between 4: Division sum: 10 ÷ 4 = 2 remainder 2 40 shared between 4: Division sum: 40 ÷ 4 = 10 200 shared between 2: Division sum: 200 ÷ 2 = 100 600 shared between 6: Division sum: 600 ÷ 6 = 100 That's 2 down. 3 left today — send the next one.
