Academic Skill: Create simple math problems using the Maya numbering system.
Teacher: Reproduce the instructions below for each group.
The numbering system used by the Mayas was based on twenty, not ten, like ours. Zero was represented by a sort of shell shaped like a football. Ones were shown as dots; fives as straight lines. With your partner make up simple math problems using the number system below. Your answers should not total over twenty. Trade your problems with another group and try to work out your problems together.
