Subtraction
By JoeBaxter
For students with a good grasp of fundamental subtraction, this set of lessons goes through increasingly complex subtraction problems. Larger values are introduced, and students are shown how to subtract one to four digit numbers with or without regrouping. Students will further be shown several useful tools, including how to subtract with a calculator, using a subtraction table, and even using mental techniques such as decomposition. Later, students are shown what subtraction looks like in a word problem and how they can subtract with an unknown value.
