A practical map of the math skills learners build through Grade 6. Exact timing varies by curriculum.
How it's taught now
Balance models and inverse operations preserve equality while students explain what each variable represents.
Three mistakes to watch for
Treating the equal sign as a signal to calculate rather than a balance.
Changing only one side of an equation.
Combining terms that are not alike.
A worked example
Solve 2x + 3 = 17.
Remove three from both sides, then divide both sides by two.
Answer: x = 7
Try this together
I am thinking of a number. Twice the number plus 3 is 17. What is it?
Give them a moment to talk it through. The explanation matters more than a quick answer.
