Twenty-one leveled sheets to practice the skill of addition and subtraction through the use of number bonds. The first level starts at understanding bonds of 5 and then increases by one for each level (bonds of 6, bonds of 7, etc). There are four levels that are mixed (mixed bonds up to 10, 12, 15, and 18). There are also three very high levels for those kids that are adding and subtracting up to 100.
