simple addition - learn to add two numbers, both from zero to ten. Keeping the numbers between zero and ten prevents the children from having to "carry the one" at this point in the learning process.
simple subtraction - also from zero to ten.
Adding three rows of numbers. The level three stage will sometimes require the children to "carry the one". By adding a few pages from the level two group, the children will become familiar with the process of adding three rows of numbers.
You'll notice in these worksheets that the top number is always "1". We won't need to carry anything other than "1" until we start learning multiplication, so at this point all of the formulas on the worksheets start with "1".
Adding and subtracting one number between 10 and 19 and one number between 0 and 9.
Adding and subtracting one number between 10 and 99 and one number between 0 and 9.
Add the numbers across. Add the numbers down. Add the answers you came up with across and down as well. Notice that the sum of the answers across = the sum of the answers down. You don't have to spend loads of time analyzing this with the kids... it just helps them start to form the basis of mathematical relationships, seeing math as more than just an exercise in memorization.
|Adding two numbers between 0 and 99. The children will often be required to carry the "1" from the "ones" column into the "tens column" in order to arrive at the answer. If the children struggle with level three, it's often useful to have them draw a line between the ones and tens columns and treat them as separate equations. (see the red line in the example to the right).|
