Your child may be able to read a clock, but what about the passage of time? This workbook is all about elapsed time, and how to both estimate and calculate how much time has passed in between hours.

This workbook will challenge your fourth grader with math formulas, shapes practice and angle activities. Kids will also learn how to find areas and perimeters, classify triangles and calculate time.

Count and convert measurements for liquids, lengths and time with this supplemental book! So many practical skills come from knowing how to measure lengths, tell time and convert units of measurement.
