Let's try a practice problem to remember how patterns can help us with addition and subtraction.
Fill in the boxes with the missing numbers.
What is the pattern? Choose the correct answer:
12-4=8. Use this to find:
Sometimes our problem is in the form of a story, or sentences. In this video, we see how to work out our number problem from the key words, or clues.
Four friends are picking fruit in an orchard. Tricia picks 16 apples, Ryan picks 29 peaches, James picks 23 pears and Laura picks 15 plums.
How many pieces of fruit were picked in total?
