5. Strategies for tutors re “the equals sign”
|
Give your learners situations with numbers and letters where the unknowns are in different places.
For example  x 7 = 56 or 18 – 5 = 24 - and 12 + a = 36 – 14. This will also help develop ideas about inverse operations, doing and undoing. Research has also shown that understanding of equality and operations can be supported by relational thinking.
An example of relational thinking is:
- What values can you give to m and n to make this equation true? 100 – m = 97 – n
- What is always true about the values you choose for m and n that make the equation true?
