The lessons in this unit focus on understanding subtraction as taking apart or separating or taking from. We start with concrete objects to build the foundation for the terms, "losing" or "minus" as something going away. For example: Four losing two is two! (4-2=2)
At Home Support:
1. Act it out- Use stuffed animals or toys to act out a story problem.
- Example- There are five teddy bears, three go away, how many are left.
2. Use flash cards with numbers on them. Put larger numbers in a pile such as 3, 4, 5, 6, 7,8 and then smaller numbers in another pile such as, 0, 1, 2, 3. Have them make a subtraction number sentence by drawing one card from the first pile and subtracting a number from the second pile!
3. Try to have your child do subtraction with real world scenarios. such as... Look there are five pieces of bread left in the bag, what if three of us eat a piece. How many will we have left? Those types of problems are perfect.
