Put six blocks in front of a six-year-old, slide two away, and ask how many stay on the table. Many children start again from one and count every block, even the two you moved. This 1st grade subtraction with cubes worksheet slows that moment down. In each of the ten boxes, a row of cubes sits above a subtraction sentence such as 6 – 2 or 8 – 5, and a pink line already crosses out the cubes being taken away. Your child counts the cubes without a line and writes the number on the dotted space. Every problem stays within 10, and one box, 2 – 2, ends with no cubes at all. A second page gives the answer key.
