Put two rows of cubes in front of a six-year-old and ask for the total. Many children start again from one and count every cube. Others look at the top row, say « five, » and keep going from there. This 1st grade addition with cubes worksheet sits right between those two habits. Six boxes hold blue, orange and green cubes, with one row above a plus sign and one row below it. Under each box, an addition sentence waits for its total, and the sums to 10 stay small enough to check by touch. The cubes never leave the page, so your child can always go back and count. A second page gives the answer key.
