Lesson Details
Key learning points
- When multiplying terms, there are not the same restrictions.
- The result of multiplication is called the product.
- ab = c also means that a = c/b
- a = c/b can also be written as a = c x 1/b
Common misconception
Rather than learning to rearrange multiplicative relationships pupils can just learn the rearrangements or use a trick.
There are many situations in school and out where this skill is valuable and understanding how to manipulate these relationships will help pupils to understand the mathematics rather than just learn a set of procedures or lots of formulae.
