- PEC #3-Math: Wed, Feb. 15 from 9:15-2:15 pm
Math: Third grade students have been working on different strategies for multiplying by 9. One strategy that we have been using is to use the distributive property and the fact 9=10-1 to multiply by nine (ex: If I wanted to find the product of 9 x 6 I would multiply 6 x 10 and then subtract one group of 6 to get my answer). Third graders also used their understanding of multiplication and division to complete fact families and worked on explaining patterns when using 0 and 1 as they relate to both multiplication and division.
Fourth grade students have been learning different strategies to help them divide. The first strategy we discussed was the partial quotient strategy. This strategy allows students to divide larger numbers by using their knowledge of place value and it also reinforces key vocabulary (quotient, divisor, dividend, remainder). They also learned how to use the area and array models for solving division problems, lesson 15 in Engage NY, and have been solving Kakooma Math puzzles.

PROJECT READING: Students identified the cause and effects of pollution from "The Lorax." They also compared and contrasted the stories "The Lorax" and "The Truax" and wrote their opinions of which story they thought was right. Many students sided with both stories for different reasons.
PROJECT TIME: Students participated in hands-on learning about the states of matter by describing their properties when holding a block, ice, water in a bag, and creating gas with vinegar and baking soda to make a balloon fill with gas. We also read and discussed a powerpoint about the states of matter focusing on the properties of each. Then assigned teams sorted pictures into categories: solid, liquid, or gas. We had discussions about pictures that could have been in two or more states of matter.
Students worked in assigned groups to sort pictures into pollution categories. This week, each team will choose a type of pollution to begin their research and become experts about that pollution in order to teach the other groups.
MAKERSPACE: Students learned how to make slime using shampoo, baking soda, and water. We discussed the properties of each ingredient. We will continue experimenting with states of matter in makerspace.
Have a FUN week of learning!
