Long Division Videos & Practice Links

We are working hard to learn the process of long division.  Here are a couple of videos that we’ve watched in class:

Screen Shot 2016-01-06 at 7.09.34 PM It is extremely important for 4th grade students to be fluent with their multiplication facts.  Students may use the XtraMath program to help improve their multiplication and division fact fluency.  We try to work on this every day in class, but it may also be done at home.

2 X 2-digit Multiplication

We are currently working hard on learning and practicing the process of multiplying up to 4 digits by 1 digit and 2 digits by 2 digits.  Just learning how to use the “old school” algorithm to solve the problem is no longer enough.  The kids have to be able to explain the process of why that “old school” algorithm works.  I’ve posted short video clips that help to show the multiplication process and what we are expecting the kids to understand and do.  Of course, it is extremely important that the kids learn and memorize their basic multiplication facts!

The Process of Multiplication

Last week we began reviewing the process of multiplying 2-digit numbers by 1-digit numbers.  We viewed the videos below to help us understand how we use the values of the digits to multiply.  Ask your child to teach you how to do this type of multiplication.  If he/she can teach it to you, then you  know he/she has learned it!

Decimals

This week we’ve begun studying decimals.  Our study of decimals includes:

  • Representing decimal numbers (tenths & hundredths) using base ten blocks and money
  • Writing decimal numbers in standard, word, and expanded form
  • Comparing and ordering decimals through hundredths
  • Relating decimals to fractions (tenths & hundredths)
  • Determining decimals as points on a number line
  • Adding & subtracting decimals (including money)

Here are some links that your child can use to practice decimal skills:

Place Value

**The X quiz that we took today over the squares & 2’s has been checked and passed back.  Please sign and return it to school tomorrow.  Our next X Quiz will be on Wednesday over the squares, 2’s & 5’s, and then Friday over the squares, 2’s, 5’s, & 3’s.

 

We are currently working on learning to read, write, and expand numbers up to the hundred billions.  We are using this place value rap to help us!  We will have a quiz over labeling the places in a place value chart on Friday this week.

Here are some other links that can help with place value:

Virtual Fraction Manipulatives

We have been working on finding equivalent fractions and comparing fractions in math.  Some of the manipulatives that we use in class are pattern blocks and fraction tiles.  The picture below will take you to a website where the kids can use fraction tiles and circles to make all kinds of discoveries such as equivalent fractions, adding/ subtracting fractions, modeling & identifying improper fractions & mixed numbers, and comparing & ordering fractions.  Not only can the fraction pieces on the site be moved or manipulated, but there is also a work space with a drawing tool that the kids can use to write the equations or fractions that they’ve modeled.  They can then take a picture of their work and email it, or even post it on their blog!  It is also a wonderful resource to use when working on fraction homework!  To check it out, click on the picture of the fraction tiles below.

Math homework this week

Math homework was given to all classes today and will be due on Thursday of this week.  If, for some reason, your child doesn’t make it home with the homework, you can re-print the homework at home–just click on the “Printing Homework at Home” link on the right side of my blog for the instructions.  The homework this week is to practice converting a mixed number to an improper fraction.  The picture below shows one of the processes that we’ve used in class–MAD Mixed Numbers!
