Lesson 1: Estimating Sums and Differences of Mixed Numbers
Main Idea: Students estimate sums and differences of fractions and mixed numbers. They learn how sums and differences of mixed numbers can be estimated by rounding each mixed number to the nearest whole number.
Standard (s): 5.NF.A.2
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
