A tree is 5 m tall. A tower is 4 times as tall. Mia says the tower is 20 m. Is Mia right?
Circle one: True False
Mia says a tower that is 3 times as tall as a 5-block tower has 3 + 5 = 8 blocks. Is she right, and if not, what should she do?
- No, she should divide: 5 / 3 blocks.
- She is right, 8 blocks is correct.
- No, she should multiply: 5 x 3 = 15 blocks.

27 · 3 x 9 = 27 cm.
36 cm · 3 times as long means 3 x 12 = 36 cm.
8 metres · '2 times as long' means multiply by 2. 4 x 2 = 8 metres.
4 · Think of the opposite: 20 / 5 = 4, so the missing number is 4.
6 · 6 x 7 = 42, so the missing number is 6.
24 · Work backwards from division: 6 x 4 = 24, so the missing number is 24.
6 · Each sandwich pairs with each drink: 3 x 2 = 6 combos.
True · Mia is right. 4 x 5 = 20 m.
No, she should multiply: 5 x 3 = 15 blocks. · 'Times as tall' means multiply, not add. 5 x 3 = 15 blocks.
12 · 6 x 4 = 24 toys, and half of 24 is 12 cars.
