This “print and go” set of balanced equation problems for students to solve are a quick, low prep addition to math stations. Students add the two colors of marbles in the first jar to find the sum and use that sum to find the missing addend in the second jar to equal the same sum. Students can use manipulatives such as marbles, two-color counters, or beans to find the missing addend. The set includes sums from 4 to 10 and a blackline master to use for creating additional problems. Two versions of recording sheets are included for accountability.
