Best match
- Number Bonds BridgeGrades 1–2Tap stones onto the bridge piers to build the number bond — the raccoon crosses when the parts match the whole!Play

- Snack Bar TapperGrades 1–3Customers walk down the counters with orders like 8 + 5 — build their cookie tray out of tens and ones and slide it to them before they reach the bar.Play
