Decimals

We have been learning about decimals in math.  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:

Parent Homework, REMIND, & Multiplication Facts

The kids’ homework folders are full of notes today!  The 4th Grade Grading Policy & the multiplication fact note need to be signed and returned ASAP.  The “Million Words” parent homework 😉 is not due until next Friday, Aug. 31. (The kids earn reward tickets when they are returned!)

I’m also asking parents to please enroll in my REMIND classes.  I have two REMIND classes:  one for my homeroom, and one for math.  I use REMIND to keep parents informed about upcoming events, quizzes, etc.  It’s also a great communication tool when parents need to change transportation methods or get messages to their kids.  To sign up for Homeroom notifications, text the message @hunter4hr to the number 81010.  To sign up for messages regarding Math, text the message @hunt4math to the number 81010.

The majority of math-related stress in 4th grade students comes from the lack of knowledge of the basic multiplication facts.  It is EXTREMELY important that students become fluent in their facts so they can concentrate and spend time on the process of HOW to solve a problem, and not just spend all of their time trying to do the computation of the problem. 

Below are some practice links to Quizlet.  Clicking on a link below will allow many options to practice a set of facts:  Flashcards, Learn, Test, Scatter, & Space Race.

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!
