Fifth grade math classes at Stratford School require students to be conversant in subtrahends, minuends, and more.

After constructing their own unique geometric and arithmetic number sequences, students challenge their classmates to determine the underlying rules. They understand the need to use variables when describing a sequence rule, and they use 21st century learning to determine how a simple change can produce dramatically different results.

Students learn to think critically about numbers, to dive deeper to determine how they can manipulate data for a desired result, and to further explore any unexpected outcome.
