Number sense is critical to the development of a child's understanding of mathematics. A number can be an object, a picture, and a symbol. Number sense develops over time. Understanding how numbers relate and their characteristics is important. Children need a great deal of time to explore with manipulatives. Some manipulatives that are very useful are Unifix cubes, pattern blocks, two‐colored counters, transparent chips, centimeter cubes, place value blocks, dominoes, buttons, spinners, and dice. Time needs to be given to freely explore the manipulatives that you will have available. This will allow the children to get "the play out" so that they will be better able to focus on the math concepts when using the manipulatives. Usually one to two weeks is sufficient time for the children to freely explore. As the children explore, the teacher can be individually assessing the children on counting by memory, one‐to‐one correspondence, instant recognition, numeral formation, and counting backwards.
When using manipulatives, there are two rules that the children need to follow: (1) Whatever you get out, you put away, and (2) Never throw manipulatives. Remember to have a specific place that the manipulatives are always returned to when the children are finished with them. Start out free exploration with only two or three of the different types of manipulatives.
According to Mary Baratta‐Lorton, author of Mathematics Their Way, there are three levels of abstraction -- concept, connecting, and symbolic. At the concept level, children are building concrete models with manipulatives and using language to describe what they have created. At the connecting level the children are still building models, but they are now connecting written numbers that have been written down for them. At the symbolic level, the children write the numbers or equations to represent the concrete model.
1. Demonstrate a positive learning attitude.
2. Develop social skills and ethical responsibility.
5. Understand and use basic concepts and skills.
6. Communicate clearly in oral, artistic, written, and nonverbal forms.
Content Connections:
Literacy ‐ Choose books from the school's leveled library that have a focus on number sense for small group instruction. Choose books that have a math focus for browsing books. Use time in the computer lab and have children compose number sentences that they will illustrate with clip art and/or using programs such as Kid Pix Deluxe 3X.
Invitation to Learn:
Tell the children that numbers often play an important part in books. Ask them if they have noticed that three is very important in fairy tales/folk tales. For example -- Goldilocks and the Three Bears, the Three Billy Goats Gruff, Rumpelstiltskin, and the Three Little Pigs. Of course, other numbers are also important. Ask if they can tell you about any books in which numbers are important.
Next, tell the children that you are going to read Mouse Count. Ask them to listen carefully for numbers in this story. Number plays an important part in this story and in our lives. Numbers surround us. All you have to do is look for them.
Instructional Procedures:
After finishing the book, ask the children, "Were numbers important to the story? Why?" Read the story a second time and use a number line as a model for the story. Ask the children, "Was the number line helpful in understanding the story?" Also, ask them, "How many mice did the snake catch the first time? The second time?" Point out to the children how the snake counted on when he placed mice into the jar. Tell the children that counting on is one way to count items more efficiently.
Lesson and Activity Time Schedule:
Activity Connected to Lesson:
Snake -- this is a whole‐class activity.
Example of a child's snake paper. First (for the s column) a three was rolled, and then a one was rolled. Next, all children stood and a four was rolled.
Play Dice Advice. Each child is given a Dice Advice strip (pdf) and nine small manipulatives.
This is a problem‐solving activity, which you will play later on in the year. Children should realize that some numbers seem to be rolled more often than others.
Family Connections:
Send home a copy of the Dice Advice strip for the children to play at home with their parents.
The teacher needs to observe how well the children recognize the dots on the die. Do they count them each time? Do they have instant recognition? The teacher should individually assess counting by memory, one to one correspondence, instant recognition, numeral formation, and counting backwards. Do the children seem to be using their prior knowledge of numbers to develop a deeper understanding of numbers?
