Math:

This week in math, the students will solve two types of division situations.  Division problems where the group size is unknown and problems where the number of groups is unknown using factors of 2, 3, 4.   Students will use tape diagrams and arrays as tools to compare and analyze problems.  Students will use arrays and tape diagrams to practice solving division problems and transition to problem solving using abstract division and multiplication equations. The students will skip count objects in models to build fluency with multiplication facts using units of 4.  We will continue using the distributive property of multiplication to solve math problems. 

Example of tape diagrams:

                                    

                                 

Things to practice at home:

Practice labeling tape diagrams to solve problem situations (homework problems this week include tape diagrams for practice).  Ask the following questions as you are solving problems:

·         Am I looking for a part? 

·         Am I looking for a number of parts? 

·         Am I looking for the whole amount?

·         What is my model showing me?

Discuss and practice analyzing problem situations comparing different unknowns. 

Continue using arrays to help solve multiplication problems using the distributive property (break apart property) to solve multiplication problems.

Practice multiplication facts (2, 3, 4, 5)

Science:

This week in Science we will discuss science safety rules and how scientists observe and infer during their explorations.  We will discuss the importance of scientists maintaining accurate records and communications.

Math:

This week in math, the students will begin to find related multiplication facts by adding and subtracting equal groups in array models.  They will model the distributive property of multiplication with arrays to decompose units as a strategy to multiply.  The students will model division as the unknown factor in multiplication using arrays and tape diagrams.  They will also interpret the quotient as the number of groups or the number of objects in each group using units of 2 and 3.

Examples of distributive property using arrays:

Things to practice at home:

Practice multiplication facts 2-10.

Create multiplication and division word problems to solve using arrays, equal groups, and multiplication facts.

Practice the commutative and distributive properties of multiplication.

Math:
This week in math the students will interpret the unknown in division by using the array model.They will begin to understand the commutative property of multiplication and practice related facts by skip-counting objects in array models.  The students will find related multiplication facts by adding and subtracting equal groups in array models.

Example of arrays to demonstrate the commutative property of multiplication:

Example of arrays to show multiplication and division:

Things to practice at home:
Practice multiplication facts 1-4 using flash cards or making equal groups.
Use the commutative property of multiplication to practice math facts.
Practice writing and solving division problems discussing what is missing in equations.

Week of August 20, 2018

Upcoming Events:
8/20 - Math District Baseline test
8/21 - Science District Baseline test
We will begin i-Ready Reading and Math test this week.

Math:

In math, the students will continue learning to distinguish between the number of groups and the size of groups to write multiplication facts.  They are learning to use arrays, counting rows and how many in a row, to write multiplication facts.  They will continue to create pictures, multiplication equations, and number bonds to model their understanding.

This week we will continue to work on understanding the meaning of the unknown as the number of groups in division and interpreting the unknown in division using the array model.  We will use the Read, Draw, Write (RDW) strategy to solve math problems. The students will also begin to study the commutative property of multiplication by manipulating arrays.  They will notice that the meaning of the factors in a multiplication sentence changes depending on the orientation of the array.

For example: 

This array has 4 rows and 3 columns. It can also be described as a 4 by 3 array.

The array can be rotated to show 3 rows of 4 or 3 by 4.

These arrays can be used to model division.  The problem will determine which way to draw the array.

For example:

Bob has 12 star stickers.  He puts them into 3 boxes.  How many stickers will be in each box?

12 ÷ 3 = 4 

There will be 4 stickers in each box.

Math Vocabulary:

Array – an arrangement of objects into equal rows and columns

Multiply - an operation showing how many times a number is added to itself

Equal groups – same number of objects in each group

Factor – number of groups and the number in each group

Equation – a statement that two expressions are equal, for example 4 x 3 = 12

Divide – separate into equal groups

Things to do at home:

Practice making arrays at home.  Talk about changing the orientation of your arrays and write the multiplication equation.

Create your own multiplication and division word problems and write the equations for the problems.

Look for groups of things at home.

Practice multiplication facts.

Upcoming Events:

8/15 & 8/15 - ELA District Baseline Testing

Friday - Music

Math:

This week in math we will begin with Module 1 lesson 1.  This module builds on students' fluency with addition and their knowledge of arrays.  Students will use repeated addition to find the total from a number of equal groups.  They will begin to understand that skip counting rows is a strategy for multiplication.

Things to practice at home:

Create arrays (arrangement of objects in rows and columns) to skip count.

Create equal groups (in multiplication, one factor is the number of objects in a group and the other is a multiplier that indicates the number of groups)
