Reflex Relay

What students practice

Students practice number bonds to 100, such as knowing that 37 needs 63, calling the teammate whose number brings the baton's number up to 100.

How to play

A runner's baton shows a number while four teammates wait; players press 1 through 4, or the arrow keys and Enter, to call the matching teammate before the runner leaves the exchange zone. A late or wrong pass costs one of three shields, a fast pass earns a quick pass bonus, four passes finish a relay, and a wrong call shows the bond before it is asked again.

Teacher Setup

Teacher Setup lets a teacher choose Grade 3, Grade 4, Grade 5-6, or All number bonds, set the speed, and choose whether a miss reveals the answer. A printable student report lists bonds to practice.
