• 38 cm

• 50 cm

Look at these number lines. Find the difference between A and B.

• 12.025

• 11.9

• 11.975

• 12

Work out the value for A, B, and C.

• A = 34.4 B = 10.9 C = 4.7

• A = 35.4 B = 10.9 C = 3.7

• A = 35.6 B = 11.1 C = 3.7

• A = 34.4 B = 10.1 C = 4.5

Here is a square. Inside the square is an equilateral triangle. The perimeter of the triangle is 54 cm. Find the perimeter of the square.

• 64 cm

• 324 cm^2

• 246 cm²

• 72 cm

• Star = 3 triangle = 30 rectangle = 108

• Star = 3 triangle = 30 rectangle = 1,080

• Star = 300 triangle = 3 rectangle = 1080

• Star = 3 triangle = 300 rectangle = 108

A turtle walks 1.6 meters every 15 minutes. How far does a turtle walk in 2 hours?

• 6.4 meters

• 3.2 meters

• 9.3 meters

• 12.8 meters

• star = 4 triangle = 1 circle = 1

• star = 2 triangle = 2 circle = 4

• star = 3 triangle = 2 circle = 6

• star = 3 triangle = 1 circle = 1

Can you find a path from 6 to 0.06? You can not use diagonal moves.

• 6 x 10 x 10 ÷ 100 ÷ 10 ÷ 100 = 0.06

• 6 ÷ 10 x 10 ÷ 1000 x 1000 x 100 = 0.06

• 6 ÷ 10 x 100 ÷ 10 ÷ 1000 ÷ 100 = 0.06

• 6 ÷ 10 x 100 x 100 ÷1000 ÷ 100 = 0.06
