Activity 01
Inquiry Circle: The Maya Math Challenge
Students learn the Maya symbols (dot for 1, bar for 5, shell for 0). In pairs, they solve addition and subtraction problems using these symbols, discovering how a positional base-20 system works compared to our base-10 system.
Analyze how the River Nile influenced the daily life and economy of ancient Egyptians.
Facilitation TipDuring The Maya Math Challenge, circulate with base-20 number cards and have students physically group and regroup counters to reinforce the positional value system.
What to look forProvide students with a map of ancient Egypt. Ask them to draw arrows indicating the direction of the Nile's floodwaters and label two ways the river supported life. Collect and review for understanding of inundation and its impact.
