Unit 2 (Rounding, Addition, Subtraction)
In this unit, the students will use place value understandings and the number line as tools to round two-, three-, and four-digit measurements to the nearest ten or hundred (3.NBT.1, 3.MD.1, 3.MD.2).
Students will use estimations to test the reasonableness of sums and differences precisely calculated using standard algorithms.
Students will use estimations to test the reasonableness of sums and differences precisely calculated using standard algorithms.
Students will demonstrate understanding in every step of the addition and subtraction algorithms with two- and three-digit numbers, as 10 units are changed for 1 larger unit or 1 larger unit is changed for 10 smaller units (3.NBT.2). Students will use these skills to solve addition and subtraction word problems.
