Building Number Sense

I want my students to have a good sense of numbers and their relationships. Math manipulatives are the key to developing this number sense.

Start with counters. They are ideal for helping children make the transition from counting by rote to actually associating number words to numbers of objects. Make sure that the counters are the same size, shape, and color. To start out, use counters that are simple and that won't distract your students. You have probably seen cute sets of counters that consist of little bears or dinosaurs. These are good for later but not for beginning to count. I like to start with square tiles or cubes.

Whenever you introduce a new manipulative, give the children plenty of time for free play. That way the kids can get this out of their system and focus on the math concept you are trying to teach.

It is important to teach your students the correct way to handle their manipulatives. Have the students practice using their manipulatives quietly. Explain that they are responsible for returning the manipulatives to you, so it is important to be careful and not lose them.

I usually pass out my counters in sets of ten or twenty. Here is a way to pass out counters efficiently, make sure you get them all back, and reinforce number sense. At the beginning of the year, have each child bring in two one dozen egg cartons. Cut off two egg holders from the end of each carton, so that you have ten egg holders. Then put one counter in each egg holder. When you are passing out counters, give each child one carton if you want them to have ten counters apiece, or two cartons, if you want them to have twenty counters. At the end of your math lesson, the students must put the counters back into the cartons. It's fast, nothing gets lost, and the students get number sense practice without even realizing it!
