Ray's New Primary Arithmetic · Lesson L · Unit 5: Multiplication
50. Adding, subtracting and multiplying in a chain
Goal: Your child follows a chain of three steps in their head.
You'll need
- A slate, small whiteboard or paper and pencil
What's in the book
Questions such as "How many are 2 and 5, less 4, multiplied by 3?" (worked: 2 and 5 are 7; 7 less 4 are 3; 3 multiplied by 3 is 9).
The lesson, step by step
Show one slowly
Work the example aloud, saying each middle answer.
Write the middle answers
At first, let your child jot each middle answer on the slate. Later, do it all in their head.
Book questions
Work through the page.
Afterwards
One chain question a day, made longer as your child gets faster.
