The Echo Grove — Read Multiplication as Equal Groups (Grade 3)
A free interactive Grade 3 math activity: read Pim's rune (like 3 × 4) and tap the grove that shows 3 groups of 4 — not the look-alike with the same total but a different grouping. Children interpret a product as equal groups (the first factor = number of groups, the second = the size of each group). Common Core 3.OA.A.1.
