Make-Ten Pyramid
Clear a pyramid of number cards by pairing cards that make the target — Make 5, Make 10, or a Big pyramid. Every deal is checked by a solver so it can always be cleared, a wrong pair just shows its sum, and undo is unlimited. Stuck? Tenley the owl shows the next pair and why. Number bonds become a card game — no timer, no score to chase, on-device, no account. Ages 6-8.

Meet the cast
Make-Ten Pyramid's number friends each embody one NUMBER BOND — the crew IS the arithmetic (each friend wears their number as dots, never a digit). Sevvy and Threeby are best friends who always make ten together. Fivefold looks for another five — two fives make ten. Captain Ten needs no partner at all. Mentor Tenley, the owl, asks which card is still missing its partner.
Sevvy
A seven who always makes ten with best friend Threeby (7 + 3 = 10)
Threeby
A three who always makes ten with best friend Sevvy (3 + 7 = 10)
Fivefold
A five who looks for another five - two fives make ten
Captain Ten
A ten who clears all on its own - no partner needed
Tenley
