In first grade, students begin to explore the relationship between addition and subtraction. By the end of first grade, students will understand that we can use addition to subtract. They will also understand that we can find a missing number by using addition and subtraction to find a missing addend, sum or difference.
This packet includes everything you need to help your students master the relationships between addition and subtraction. Every student learns differently, and every district has different methods of teaching these relationships, so you will find practice work for BAR MODELS, WHOLE PART PART CHARTS, and NUMBER BONDS! This packet also includes word problems to help your students identify missing pieces of an addition or subtraction problem. REMEMBER: when we ADD, we put the two SMALLER numbers together to get the SUM or the bigger number. When we SUBTRACT, we ALWAYS start with the BIGGER number! You will also find practice work for BALANCED EQUATIONS and worksheets that help students IDENTIFY balanced equations.
The objectives for these worksheets include:
IWBAT use addition as a strategy to find the missing WHOLE
