3rd Grade Math/Science Weekly Update (Dec. 6-10)
This week in 3rd grade Math and Science...
- In math, we will continue using our problem solving mat (PSM) to help us organize and solve multi-step word problems involving the operations of addition and/or subtraction. We will be reviewing how to use our problem solving organizers to help us show and represent the various addition and subtraction story problems using equations, pictorial models, and strip diagrams.
- In science, we will be taking our unit assessment on the different kinds of energy we’ve explored so far (sound energy, light energy, and thermal energy) this Friday, December 10th. We will be reviewing for our upcoming unit assessment this Thursday, and the study guide we'll be using for our review will be sent home that afternoon. During the course of the week, we will also be learning about mechanical energy as the energy that motion or position gives to an object. We will explore how we use mechanical energy every time we lift or move an object or use a machine with moving parts. We will also be observing and exploring how motion and position can be changed by pushing and pulling objects, and we will spend some time discussing how forces such as magnetism and gravity act on objects.
