Maths Problem Solving Activities
Some fun activities for your children to do to improve their maths problem solving skills are listed below.
Addition and Subtraction Problems
Puzzling Sums and Differences
You can combine the digits from 1 to 9 and then add or subtract to arrive at an answer of 100. Below are just a few examples. Note that the digits are used in order and they can form a number such as 67 or 89.
123 + 4 – 5 + 67 – 89 = 100 12 + 3 – 4 + 5 + 67 + 8 + 9 = 100
123 – 45 – 67 + 89 = 100 1 + 2 + 3 – 4 + 5 + 6 + 78 + 9 = 100
Count Back to Zero
Two or more can play this game. Start at any number, such as 20. The first player counts back by one, two or three. The next player continues from the last number mentioned and counts back by one, two or three. The winner is the person who counts to zero.
Try to Spend It!
Use catalogs and newspaper ads to “shop.” Select an item and round its price to the nearest pound. Try spending £1000. How many items did you buy? Keep track of the items bought and their costs.
Try spending £10,000; £100,000 or £1,000,000
Multiplication and Division Problems
Wages and Salary
Use a wage of £4.75 per house to calculate a yearly salary for someone working 40 hours a week for 52 weeks.
Next find several ads in your newspaper’s Jobs Available section that advertise yearly salaries. Calculate a weekly (divide by 52) and a monthly (divide by 12) salary. Compare these wages and salaries to the salaries received by various entertainment figures in sports, TV and film.
