Math in Our World: Gymnastics

Sasha loves to do gymnastics. She tries to record how many different exercises she does each day.

Sasha forgot to record the number of cartwheels she did Monday. She knows it was more than 10.

She didn’t count the number of flips she did Tuesday, but she knows it was at least 5.

A table shows exercises for Monday and Tuesday. Cartwheels: Monday blank, Tuesday 12. Flips: Monday 8, Tuesday blank. Back handsprings: Monday 17, Tuesday 18.
