# December 8-12 Math/Science Update

### By: Rachel Withers Math Facilitator MIS

## It's the MOST Wonderful Time of the Year!

## 3rd Grade
*3.OA.5 Apply properties of operations as strategies to multiply and divide. Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.) *3.OA.6 Understand division as an unknown-factor problem. For example, find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8. *3.OA.8 Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
LS 2.3.2 Identify major parts and functions of the muscular system | ## 4th Grade
*4.OA.1 and 4.OA.2 Solving word problems related to multiplication and division; interpreting multiplication equations as comparisons- 5 x 7=35 means 35 is 5 times as many as 7 and 35 is 7 times as many as 5. *4.OA.4 Factors and Multiples *4.NBT.6 Division *4.NBT.5 Multiplication
*ESS.8.4.10 Weather-related natural disasters *ESS.9.4.1 Changes to earth's surface-volcanoes | ## 5th Grade
*5.NBT.7 Adding and Subtracting Decimal numbers
*LS.2.5.7-10 Photosynthesis and Cellular Respiration |

## Resources

As you probably know, we are a Google school. The computers our kids are on each day are google chrome books. It is important that they are proficient with this technology for classroom lessons and even state tests that will be administered using it. This site gives lots of tips and tricks for Google.

Prodigy Game is a great way for you to set up a free account for multiple kids. This puts a fun and competitive spin on the standards!

Kahn Academy...This site has excellent demo lessons for each standard. You can create a profile (free) for your child or just search for videos on whatever topic they are studying in their classes.

LearnZillion...You can create a free login for your child to view lots of outstanding video demonstrations of specific content topics that they are studying in their class at the time.

Arkansas Curriculum Frameworks for Science are located on this page. These are the current standards that we teach in science. However, we will be transitioning to the Next Generation Science Standards in a few years. I will keep you updated on this as we learn more.

IXL...this is a great site for practicing math concepts. If you go to the site and find the standards for Arkansas you can click on the specific standard your child is working on this week (notated above). You can do a few things a day free, but it is unlimited if you pay for a membership.

PTA...this is an outstanding guide for you guys to consider when understanding the common core state standards.
