Day 131 – Collecting Jumping Jack Data

Students came in and read this on the board:


Some thought this was somehow an April Fool’s joke… but instead, I wanted them to unknowingly create their own data.  They stretched their arms, their legs, spread around the room, 3..2..1 GO!  They jumped for 50 seconds, counting their jumps in their head.

7th graders took a STAAR writing test today so I did not meet with them.
