Tips for Parents
▸ Why It Matters A section alone can fit several solids. Use the printed face clue as well to identify one answer. Worked example: Two equal circular bases and one curved side. → A ▸ Getting Started Choose one problem and describe what is printed before answering. Keep a finger or small paper marker at the place being checked. Read any written condition aloud. Record one observation at a time so you can return to the exact step that needs attention. Two equal circular bases and one curved side. → A ▸ If They Get Stuck If the answer differs, return to the first step where the explanations disagree. Hide the other problems while checking this one. Ask which printed clue supports the choice, and allow a change of answer after checking. An error here is a reason to revisit that step, not a measurement of intelligence. ▸ Praise Points Keep feedback short and tied to an action: “You checked each step.” Let the child point out a correction they made, then try another problem without rushing. Stop when attention drops and return later if useful. Finishing every problem in one sitting is not required.
