Four Operations with Decimals
This session is packed with fun projects, including setting up a super fun Family Math night for your whole family, learning how to run a Fundraising project (and well able to tell how profitable you are), take a side-trip into the world of prime numbers, and weave our way through a Rational Number maze!
Since this week is our final week in decimals, also review all four operations: addition, subtraction, multiplication and division, and focus on practical application of how we use decimals in everyday life. We'll review both decimals and fractions before we move onto our next block.
Advanced students will get to work through the type of math that astronomers get to use when they are making their scientific discoveries!
Download your Decimals #4 Workbook
To help you with your daily practice, I've put together a set of workbooks. You can use these or your own workbooks as long as it covers decimals. Plan to complete 4-5 pages per day. After you complete the pages, you may check the answer key.
Decimals Workbook #4
I've put together a set of videos that will walk you through these workbooks, so grab yours and let's work together. Plan to complete 3-4 pages per day. After you complete the pages, you may check the answer key.
Decimal & Fraction Review for Beginners & Intermediates
This is a large card set that will help you stay in practice over our break between math blocks. Do at least one from each section and have fun reviewing your math skills so they stay sharp!
Run a Fundraiser Math Project
This session covers lots of applications of all four operations of decimals as you raise money for your new playground in this Fundraising Math Project! You'll first map out how to raise money, estimate how much you expect to earn, and then calculate (using accounting skills) how you actually did. You'll wash cars, host a movie night, sell plants, give away desserts for free, and collect donations! You'll practice estimating, rounding, averaging and more as you work through specific projects.
Family MATH Night!
We're going to have fun practicing our math skills by setting up a series of math games that are fun for the whole family! You can modify the games to match the skill level of each person (especially younger kids). This packet is just to get you started. Inside you'll find tangrams, horse races, dice games, and more. I want you to come up with your own games in addition to the ones in this packet. You can also use any of the games from the past 13 weeks of math content that you have really enjoyed!
Rational Numbers Maze
A Rational Number is any fraction with a non-zero denominator. Example: 1/2, 1/5, 3/4
Whole numbers are also rational numbers:
7 = 7/1
Decimals are also rational numbers:
0.5 = 1/2
Prime Number Trees
A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29.
Prime Number Pencil
This is a fun and unique math toy that you can use when you do your homework! Prime numbers that are truncatable are still prime numbers when you remove one of the digits on the end. If you remove digits from the left side, one at a time, and the number stays prime, then it's a left truncatable number (like 9137). The number 739 is right-truncatable, because when you remove digits one at a time from the right, the number remains prime. There are numbers that are both left and right truncatable, like 317. We're going to use the largest left-truncatable number (HINT: it's 24 digits long!) and truncate it every time we sharpen our pencil.
Decimal of the Day
We're going to continue our Decimal of the Day practice from last week! This is a fun way to practice all of the operations with decimals on a daily basis. Do NOT print out the entire packet (it's nearly 100 pages). Pick the decimal you want, and watch the video first!
Advanced Level Math Class
Advanced students will focus on doing calculations as well as working on practical application of decimals. You'll need to have a firm grasp of decimals (operations like adding, subtracting, multiplying dividing) as well as converting between fractions and decimals in order to go through the content covered in the Advanced level.
Astronomy Labs
This week we're going to do calculations just like real astronomers do when they are figuring out distances, speeds, and sizes of things that are far away based on photographs.
Math Challenge
Each session, I have a special Math Challenge for you to work on after you work through some of the content in this area of math. The goal for these special math challenges is for you to be able to communicate your great ideas with your family and friends, without them being in a math class or having any knowledge of a specific area of math. You should be able to convey your great ideas to most people that are interested in hearing what you have to share. Many families find this part of the math program exciting for them to participate in with their student!
Solution to Decimals Week #6 Math Challenge
The water level stays the same. An ice cube floats only because its water was expanded during crystallization; its weight remains the same as the weight of the water that formed it. Since a floating body displaces its weight, the melted ice cube will provide the same amount of water as the volume of water it displaced when frozen.
