Students began a new unit in math focused on linear measurement. Unit goals include measuring length and counting up to 120 length units and solving addition and subtraction story problems with unknowns in all positions. Last week, mathematicians are measuring the length of objects by iterating length units (connecting cubes, centimeter cubes, paperclips), comparing lengths of objects, and exploring longer than and shorter than language. They learned the conventions of length measurement and representing measurements with a number and the name of the length unit, gaining understanding that the length measurement of an object is the number of same-size length units that span it without gaps or overlaps. This week, students are solving compare, add to, and take from story problems about measurement.
