 1 The distance from the flag pole to the park gate is $$1\frac{1}{4}$$km. The distance from the park gate to the lake is $$1\frac{1}{3}$$km. Huey walks from the flagpole to the park gate then continues on the the lake. How many kilometers does he walk altogether? ☐= ☐ ✓ ✗ 2 Calculate the unknown length in this diagram. All lengths are in centimetres and the diagram is not to scale. ☐= ☐ ✓ ✗ 3 How many glasses with a capacity of $$1\frac{1}{8}$$ litres can be filled from a barrel with capacity $$11\frac{13}{16}$$ litres? ☐= ☐ ✓ ✗ 4 Calculate the area of this rectangle in square inches. All lengths are in inches and the diagram is not to scale. ☐= ☐ ✓ ✗ 5 Evaluate $$3\frac{2}{3}+2\frac{1}{8}-1\frac{1}{6}$$ ☐= ☐ ✓ ✗ 6 Evaluate $$4\frac{2}{3}+5\frac{1}{7}\times 1\frac{1}{9}$$ ☐= ☐ ✓ ✗ 7 Rosalie thinks of a mixed number. She multiplies her number by 3 and then subtracts three and a three quarters from the product. She ends up with $$4\frac{7}{8}$$. What was her original number? ☐= ☐ ✓ ✗ 8 Roger thinks of a mixed number. He adds one and a half to his number then doubles the result. He ends up with $$5\frac{5}{7}$$. What was his original number? ☐= ☐ ✓ ✗ 9 What is the average (mean) of these three mixed numbers?$$3\frac{1}{2}, 4\frac{7}{10}, 1\frac{2}{5}$$ ☐= ☐ ✓ ✗ 10 Dr Percy Cod has a plot of land measuring $$21\frac{7}{8}$$ acres.

One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.
