Math Problem of the Week
A teacher wanted to buy some science supplies for her class. She wanted to set up a center in her room where students could explore magnets during their free time. She looked in a catalog for science supplies and found those prices. .
Item / Quantity / CostLarge bar magnets / set of 2 / $10.95
Small bar magnet / each / $2.75
Large horseshoe magnets / each / $7.95
Small horseshoe magnets / each / $4.50
Disk magnets / set of 4 / $4.50
lodestones / Set of 10 / $7.95
She has $50.00 to spend. What materials would you recommend she buy for the science center? Remember, you can only spend $50.00, and you want to have a variety of things for students to explore. Write a short paragraph about why you chose the items you did.

Name that Insulator….Name that Conductor
Ask one students to name an object. The next student identifies it as a conductor or an insulator and then names a new object.
Each student participating takes a turn. Keep the pace quick as you can and continue around the room. If the group disagrees about whether the object is a conductor or an insulator, students’ can use a conductor detector to find out.

Math Problem of the Week
The students in Mrs. Ray’s fourth grade class had a question:
Do all brands of batteries last the same length of time, or do some kinds keep on going after the others run out of energy?
The students decided to do an experiment. They agreed they should use brand new C-cells for their test., Here is a list of the C-cells they got.
3 Charger industrial strength C-cells
3 E-Z Volt alkaline C-cells
3 Amp-Champ alkaline C-cells
The students connected each cell to a motor and let it run each day while they were in class, and unhooked it at night when they went home. They kept track of the numbers of hours each motor ran. Here are the results they recorded,
Kind of C-cell / #1 / #2 / #3Charger / 30 hours / 25 hours / 20 hours
E-Z Volt / 30 hours / 40 hours / 35 hours
Amp-Champ / 25 hours / 40 hours / 40 hours
- Based on the data, which brand of cell would you buy?
(show your work here) ______
- Explain why your chose that brand.
