Our Estimating (Grades 1-3) lesson plan enables students to define and use estimation for adding and subtracting by first rounding a number. Students are asked to estimate the lengths of various objects in their classroom, measure it exactly, and then tell if they were close or not. Students are also asked to complete problems in which they first estimate the answer and then find the exact answer, demonstrating their understanding of the lesson.
At the end of the lesson, students will be able to define and use estimation. The students will be able to use estimation for adding and subtracting by first rounding a number.
