Unit Summary
In this unit pupils will represent the 2x 10x table in different ways and use 2x 10x table to solve problems. They will explain the relationship between adjacent multiples of 2/10 and that factor pairs can be written in any order.
Lesson Summary
You will learn to use knowledge of the 2 times table to solve problems.
Key Notes
- Skip counting in 2s can be used to solve problems involving groups of 2
- Identify the group size and the number of groups in the problem.
- The group size and the number of groups are the factors of the multiplication.
Vocabulary To Learn
- Skip counting: Counting in steps of equal size. For example, skip counting in twos means to count in equal steps of two.
- Factor: A factor is a number which exactly divides another whole number.
- Product: A product is the result of two or more numbers multiplied together.
