3rd Grade Ms. Fritzie
Third Grade students are to make sense out of their world, to see the mathematics all around them, and to be able to begin to talk about the math in informal terms, and to begin to translate those informal terms and ideas to formal mathematics. It is the teacher’s job to see that there are many experiences for students to grow in these critical areas.
3rd Grade Sample Question
Students should work in partners to create their posters. Once the posters are completed, partners present their strategies and conclusions to the class.
Materials:
- coins and bills
- Newsprint or other large paper, pencil, and crayons
The Problem:
While at the grocery store, Ms. Fritzie bought 2 cans of pork and beans for 89 cents, three pounds of grapes for 69 cents a pound, and 2 pints of creams for 89 cents. “I have a $10 bill and should receive $7 in change,” she told the clerk.
Help students with any vocabulary that is new to them. One of the benefits of using Ms Fritzie is that you do have a great deal of vocabulary that can be introduced as needed to solve the problem. Student partners must then decide whether Ms. Fritzie’s answer is reasonable or unreasonable. They should draw Ms. Fritzie’s face and put a thought bubble that describes what Ms. Fritzie is thinking.
They should then create a poster using pictures,
numbers and words which will prove whether Ms. Fritzie is reasonable
or unreasonable.
Once posters
are complete,
student pairs should tell how they solved the problems. The
class should listen to each presentation. Ultimately you want the class
to be able
to compare the
presenting solution strategy to their own strategies.
3rd Grade Sample Poster
This student chose to estimate answers, which is quite appropriate. He knew that the amount Ms. Fritzie would pay would be more than $3.00. If she wanted about $7.00 in change from a $10.00, she would need to spend around $3.00.
