Objectives
My students usually come to my class well below grade level in reading and math, and to address the low math scores I will also address the reading skills. My students who are low in reading and comprehension, also struggle in math because there is a great deal of reading that goes along with math.
My goal in this unit is to give my students a good foundation for solving addition and subtraction story problems that will prepare them for the upper grades with the knowledge they will need to be successful in mathematics.
My unit will address all of the Common Core standards2 listed below, in addition to reading and comprehension skills.
Common Core Standard 1.OAA.1,Using addition and subtraction to solve problems with in twenty, in all situations including putting together, taking apart, and comparing two and three quantities with unknowns in all positions. This unit will also be working on other standards, including 1.OA.B.4: Understand subtraction as an unknown addend problem and some of the place value standards – 1.NBT.B.2 (which has A, B and C parts) and 1.NBT.C.4, adding within 100.
These are the main standards that I had in mind while writing this unit. It includes all six change problems, all six comparing problems, and both part, part, whole problems.
I will be relating addition to subtraction to make sure the students understand that they are inverse operations, and help students make the connections to the associative and commutative properties in word and linear problems. I will tell my students, "It doesn’t matter in which order we add two numbers, or if we have three numbers to add, it doesn’t matter which two we add first". Understanding the inverse relationship between addition and subtraction will help students to master all math objectives in the first grade.
