Squirrel's Fair Winter Piles — Equal Groups & Arrays (Grade 2)

A free interactive Grade 2 math game for arrays and equal groups: help the squirrel sort its acorns into FAIR winter piles. Draw a line to cut the rows into piles that are all the SAME size, read how many acorns are in each pile, and tap the number in — the equal-addends equation (like 5 + 5 + 5 = 15) appears and the piles sparkle. Unfair piles can't shine together. Partitioning a rectangular array into equal rows and writing it as a sum of equal addends is the heart of Common Core 2.OA.C.4.
