At the end of January, our focus will be on Greatest Common Factor (GCF) and Least Common Multiple (LCM). Your child will need to know this in order to be able to compare and order fractions.

We are learning about rational numbers (decimals and fractions). Students should be mastering decimal place value and comparing and ordering decimals. Your child should know that they must compare the decimal numbers before they can put them in order.

In October, we are working on computation. Student should be able to estimate and find the sum, difference, and product of whole numbers. They should be able to add and subtract larger numbers with and without regrouping.

They also need to be able to multiply a 3-digit number by a 2-digit number. Please help your child by practicing at home.

The week of September 18th, we will be working on comparing and ordering whole numbers. Students should be able to identify and use the symbols for greater than, less than, equal to and not equal to. They will compare two whole numbers expressed through the one millions, using symbols (>, <, = or ≠). Students will also order numbers from least to greatest or greatest to least expressed through millions (limited to four numbers).

One way is to compare numbers is to use a place value chart. After the numbers have been entered into the chart, students will start at the left most place value to check to see which number in that place value is greater. The larger number has the greater value. If the numbers are they same, they continue by moving to the next place value to the right until they find the greater number.

Another way is to compare numbers on a number line.

Our first unit in math this year is place value. Students will be identifying the place value, through hundred millions, for each digit in a whole number. They will read whole numbers through the hundred millions place. Students will be able to match numbers in standard form to their written form. They will be able to write whole numbers through the hundred millions place in a variety of forms.

Each group of three numbers is called a period. The place is the word for its location on the chart. The value is how much the number is worth. And the digit is the name of the number in each place.
