Students will spend a year solving the mystery of the pesky Math Riddler! They will use third grade Common Core math standards that are written at three differentiated levels in order to solve a riddle for each unit. Then, when they take the test at the end of the unit, a letter will be revealed that shows the identity of this math bandit. Pre and Post Progress monitoring is included in each unit. The kids love guessing the riddles and are either proud that they guessed it or surprised at the answer - either way, they are having loads of fun while learning math! Watch for more units to come - there are 16 for the school year.
