Math Update

This Week in Math...

Our focus this week will be on long division and decimal addition and subtraction, both review concepts from fourth grade that need additional time and practice to master. Students will also begin working in their Problem Solving Journals with a daily story problem. We'll use the problem solving organizer as a way to focus on the problem solving process: Read, Think, Solve, and Check.

Multiple Strategies for Multiplication

Most adults learned one way to multiply and divide. The traditional algorithm is still taught; however, today's students are introduced to alternative methods as well. By teaching students multiple models, they can choose which one(s) fit their personal learning style. The model a student chooses is often determined by the level of his/her conceptual understanding.

A great starting point for developing a strong understanding of multiplication is the area model, which is often referred to as the box model. This model provides a visual representation of the distributive property of multiplication. Students are easily able to conceptualize multiplication and it helps them make sense of the traditional model when they are ready to use it.

Partial products is similar to the box model since it also uses the distributive property. It can be used as a bridge for students between the box and traditional models.

The lattice model has been used for centuries in many different cultures. Although it looks quite different, it actually is based on the same principles as the traditional model but uses diagonal columns to represent place value. It is an efficient strategy for students who are fluent in their basic math facts and have a strong conceptual understanding of multiplication.

As parents, it can often be difficult to support our children at home if they are using a strategy that is unfamiliar to us. Please allow them to use the model that works best for them, and if you'd like to learn more about it, check out our class Blendspace page for videos that explain each of the strategies above. Your child can login with his/her school Google account.

Tech in the Classroom

Check out the new addition to our classroom....Blendspace! This online tool allows for students to review previously taught concepts as well as current lessons. What a great way for students to practice at home, study for tests or review for retests! It's also helpful for parents to see what your children are learning in math!

Retests

Students may now retest for the following SOLs:

5.11 Measuring Angles

5.12 Angles and Triangles

5.7 Order of Operations

Retests are taken in class during independent work or center time. Retest grades are averaged with the original test score and are reported on the SOL Report issued with report cards. They must be completed by October 9th to be reflected in this quarter's grade. Scores will be reported in your child's agenda.
