Exploring Addition and Subtraction. Addition and Subtraction Teaching Ideas. Unit_4_Addition_and_Subtraction. Modeling Subtraction: Overview. Subtraction involves three different types of situations.
The first, and the easiest for children to learn, is separation, or taking away, in which one quantity is taken away from another to find out what is left. The second is comparison, in which two quantities are compared to find the difference. The third is part-whole, in which the quantity in the whole set and one part are known, and may be used to find out how many are in the unknown part.
Early instruction should provide many opportunities for children to explore the three types of subtraction situations. Children learn the meaning of subtraction through concrete experiences and then learn to record subtraction in horizontal and vertical forms. Children were introduced to subtraction in Kindergarten and have experience with separating and comparing groups.
Subtraction is the inverse of addition, and although it is a different concept, it may be taught by using similar materials, models, and methods. Adding and Subtracting.

Investigations addsub_2ed. Addition & Subtraction Games. Students place markers on the numbers 2-12.
Students toss two 6-sided dice, find the sum and remove a marker from that number, if there is still one. The first player to remove all markers wins the game. This game can be used as addition practice or as an introduction to the probability of the different outcomes of rolling two dice. This game was developed by a Monmouth University student for the Probability Fair. Download the Face Off! Five Frames and Guided Math Groups. Posted on December 10, 2010.

Different arrangements help children to see and discuss different ways to name a number. Ten frames are another tool to use to build subitizing skills. Subitizing is a fundamental skill in the development of students’ understanding of number (Baroody, 1987). Here are some game ideas. 1. 2. 3. 4. Great Resources for Subitizing: There is a new video out by Marilyn Burns called Number Talks that shows a teacher using dot cards and ten frames.
