The SumPals cast
Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.
-
Sumi Add & subtract (counting on / back) — a warm acorn-orange squirrel kid who hops forward and back along a number line to add and take away; dotted jump-arcs mark each equal hop -
Pippa Number bonds / fact families (part–part–whole) — a soft cream-and-grey rabbit kid who splits a pile into two parts and joins them back; two little baskets and one whole basket beside her -
Tenny Place value (tens & ones) — a friendly many-segmented centipede kid whose ten body-segments bundle into a ten-rod and unbundle into ones; a tidy ten-rod and loose unit-cubes beside her -
Zippy Fact fluency (anti-shame) — a quick bright hummingbird kid who recalls a fact in a snap and helps you practice till it pops; a gentle glow, never a timer or a buzzer
