Think Through Math
Think Through Math is an adaptive, online learning program that is currently being funded by the Texas state legislature as part of the Texas SUCCESS (Students Using Curriculum Content to Ensure Sustained Success) program. The legislature has funded the program for the 2013-2014 school year for grades 3-8.
Students will practice as a whole class during computer lab and will be able to use at home. Students have username and password--- look in the agenda and ask them. They will also bring home a letter explaining how parents can log on. It will also have the student log in and password.

Multiplication
The fourth grade math curriculum introduces many new
concepts very quickly! We are working on
2-digit by 2-digit multiplication this week. We will begin division in 2 weeks!
Please keep working on multiplication facts at home.
-Mrs. Chu
Ways I Can Help My Child
Learn Their Facts
·
Keep a set of flashcards in the car. Have
your child practice them on the way to school, to the grocery store, or on the
way home.
·
Quiz your child in the car or at home. Just
15 minutes a night will help!
·
Use free online math fact games!
·
Once your child knows one set of facts, ask
them “What number times 2 equals 8?”
This will help them when we start division.
·
Another way you can quiz them is to ask,
“What is the product of 4x5?” This will help build your child’s math
vocabulary.
·
Create a memory game. Using index cards write
the multiplication fact on one card and the answer on another card.
·
Play “Multiplication War” –You will need 1
deck of cards (take out the face cards). Each person flips over 2 cards and
multiplies them. Whoever has the higher product (answer) wins those 2 cards.
********************************************************************************************Our class started
working on multiplication concepts this week. In the coming weeks we will be
starting division concepts. It is imperative that your child be able to
recall their multiplication facts 0-12 to be successful in math this year.
I highly recommend using multiplication and division
flashcards or using online math fact websites. Flashcards can be purchased at
Dollar Tree, Walmart, or Target.
My class webpage has
many links for students to use at home.
You can help your child learn them by asking them in the car, “What’s 2
x 7?”
Starting this Friday,
your child will be having weekly multiplication facts test. We will start with 0
and 1 this Friday. Next week they will have a test on the 2s. By December
multiplication facts 0-12 are expected to be memorized.
If you would like a set
of multiplication flashcards, please let me know and I will copy a set for you.
Thank you so much for
your continued support!

Next Week...review of characteristics of the SUN and Rounding
We'll view Brainpop on the SUN to review patterns and its role as a major energy source.
Rounding to thousands--Numbers from 4 digits. We'll use cloze sentences to help students focus on what number value makes it round up or down.
Sample of student interactive note on rounding--
Flipchart to review rounding---We used roller coaster to help us round!
Here's a sneak peek of what's ahead in math.

Here's a sneak peek of what's ahead in math.
Video on Rounding
Here are a few examples of rounding numbers to the nearest hundred:
When rounding numbers to the nearest thousand, underline the thousands digit and the digit to its immediate right. Round the number by focusing only on the two underlined digits and, when you’re done, change all digits to the right of these to 0s:
Even when rounding to the nearest million, the same rules apply:
Subtractions
We've been focusing on decomposing numbers from word problems using subtraction: take away, comparative, and missing part.
*********************************************************************************
SUM DOG is an interactive game that students can sign up to review the concepts we learned at school about subtraction.
Math Facts
Students can also go to XtraMath to practice math facts. Students should know their pins from station works and computer lab times. The classroom code is CV5N5C55. If they forgot the pin, just email me and I'll send it to you.
Remember, fluency demands more of students than memorizing numbers, it rests in a well-built mathematical foundation of three parts:
1. Understanding the meanings of operations and their relationships to each other.
2. Knowledge of a large repertoire of number relationship, including addition and multiplication "facts."
3. Thorough understanding of the base-ten number system.
