Equivalent ratios — build matched groups
Show complete groups with drawings or counters.
Follow-up task 1
A model uses 2 triangle counters for every 3 circle counters. Sketch three complete groups. Count both totals. Does 6 triangles with 7 circles meet the rule? Explain.
Equivalent ratios — explain the shared factor
Show the factor in both quantities and explain your thinking.
Follow-up task 2
A pattern uses 4 square tiles for every 7 round tiles. A larger pattern has 21 round tiles. Find the square tiles. Show the factor in both quantities and explain it in words.
