For the following problems, write two different equations that represent the total distance that Amber biked. Trip 3 ________________________________________________________________ 2 blocks 10 blocks Equation 1: ____ + ____ = ____ blocks Equation 2: ____ + ____ = ____ blocks Trip 4 ________________________________________________________________ 5 blocks 12 blocks Equation 1: ____ + ____ = ____ blocks Equation 2: ____ + ____ = ____ blocks Grade 1 1.OA.C.6 Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on making ten (e.g. 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to ten (e.g. 13 4 = 13 – 3 1 = 10 1 = 9); using the relationship between addition and subtraction (e.g. knowing that 8 + 4 = 12, one – – – knows 12 8 = 4); and creating equivalent but easier or known sums (e.g. adding 6 + 7 by creating the known – equivalent 6 + 6 + 1 = 12 + 1 = 13)
