Upcoming Events: 8/29 - Early Dismissal 9/3 - Labor Day - No School Resources this week: 8/27 - Music 8/29 - P.E./Media 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. Math Helpful Videos:
Science: This week in science we learn about the scientific method. We will discuss testable questions used by scientists and the process of conducting investigations.

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.
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)
