Choral Counting: Start at 6; count up by 5

Choral Counting is an invitation; it provides an opportunity for each student to generate important mathematical ideas and for teachers to be curious about their students’ thinking. (Franke, pag.)

I wonder what can be learned from using a number line or ten-frames to shed more light on the patterns naturally found from members of the chorus.

This week, choral counting by starting with 6 and counting by 5s, the learners began adding “because…” to what they noticed. #Awesome

It was said “To move from one row to the next row, you add 30, because 6×5 is 30.” Using the number line shows that to move from 6 to 36 there are 6 hops of 5 or a distance of 30. It is a regularity that repeats.

The next comment was “Each term on the diagonal going from the top left to the bottom right increases by 35 because 7×5 is 35.” Again, the number line shows 7 hops of 5 from 6 to 41, 11 to 46, 41 to 76, and so on.

What tools are within reach of learners as they deepen their numeracy and understanding? What is to be gained when we both author and illustrate mathematical understanding?
