Explain expressions with Star Forge

Make a prediction and investigate

Play a short Star Forge run. Write down one expression before evaluating it, marking which operation should happen first.

Discuss the evidence

Compare your written evaluation with the game’s feedback. Explain each operation rather than using the score as the explanation.

Try it beyond the activity

Change one number or operation and evaluate the new expression away from the game. Suggested Grades 5–10; select tasks that fit current classwork.

Record your thinking

Learning goal: Spin constellation reels to build equations that match the star target exactly. Earn stars, buy wishes, and shop between levels, math is how you count your way up.

Before you begin: Preview the controls and first task. Choose a learning goal that matches your learner’s current work.

Check understanding: Ask for one observation, the evidence that supports it, and a question to investigate next.

A score records play performance. Ask the learner to explain a decision and try a related task outside the game.
