Teach the Cast

Some of EquationQuest’s cast are still learning. When you teach them, YOU learn it best — catch what they get wrong, then quiz them.

Teach the connections

Show how the equation-solving ideas connect

You've helped them one at a time. The real understanding is how the ideas CONNECT — teach that next.

Undo (inverse operations) × Lever (keep both sides balanced)

Undo says "subtract 3 to peel it off." Lever says "keep both sides equal." How are those one move?

Spread (distribution (clear parentheses)) × Solo (isolate the variable)

In 2(x + 3) = 10, why can't Solo isolate x until Spread has gone first?

Capstone — solve 2(x + 3) = 10 together

One equation, three ideas. Bring in the right cast member for each step of 2(x + 3) = 10.

First: the x is stuck inside parentheses. Who frees it?

Who do you bring in?

Next: peel the +6 away. Who keeps it legal?

Who do you bring in?

Finally: x is stuck to a 2. Who gets x alone?

Who do you bring in?
