Students learn to write fact family problems. Fact families all use the same number. Using a whole, part, part mat, students use cube trains to write two different addition problems using the same numbers- 2, 8 and 10 (2+8=10, 8+2=10). For the subt...raction problems, students use the same cube trains but start with the whole (10) and then break it down into the two parts (2, 8). Write the subtraction sentences with the same numbers- 2, 8 and 10 (10-8=2, 10-2=8).[more]

Using counters, students will learn how to write a subtraction problem and determine the answer. Count the objects in the whole group, cross out to take away and write how many are left. 9 - 4.

This short video is a great resource to introduce subtracting with manipulatives. Students will see the number decrease as the jellyfish disappear. (0:54)

In this cute animated video, young students will learn how to subtract with cookies in a cookie factory. This would be a good tool for auditory learners. This is also a great resource to introduce and/or remediate subtraction in the early childhood c...lassroom. (2:40)[more]

Students learn how to write subtraction problems vertically (across the page) or horizontally (up and down the page.) One problem is demonstrated 5 - 4 = ? User clicks through the slides.
