Numbers in Multiplication Table (Open Up) : This task will help introduce the first Big Idea, that factors and multiples can be used to find relationships between numbers.Mr.Anker Tests: Interactive activities and games for dozens of math skills. This is combined into a game-based system of fun math learning. Zapzapmath: Zapzapmath has over 150 math lessons designed to incorporate higher order thinking skills in the fields of creation, evaluation, and analysis. Choose a Kahoot to match your desired skill or create your own.
Players answer questions on individual devices (Ex: Chromebook, iPads) while games are displayed on a shared screen (Ex: Smartboard or TV). Kahoot: Kahoots are fun, learning games best played in a group setting. This means that they will NOT work on iPads unless you are running an app that allows Flash to play such as Puffin. Most of these activities are Flash-based. Interactive Sites for Education: These interactive activities work great on your interactive whiteboard, computer, laptop, or Chromebook for whole group or small group instruction or use in the computer lab or at home for individual learning. Mr.: offers interactive games specifically designed to pinpoint one or several essential concepts to make the learning process more interactive and enjoyable. Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard so that students may study at their own pace both in and outside of the classroom. Virtual Nerd: Virtual Nerd provides video tutorials as a supplemental resource for both students and teachers. They are also useful for students who may need reinforcement, remediation, or differentiation. The following apps, websites, and smartboard lessons can be used throughout the unit, as needed, during small groups, lessons, to reinforce standards.
Fractions, decimals, and mixed numbers can be multiplied and divided. Positive rational numbers in different forms can be compared and ordered. Equivalencies exist among fractions, decimals, and percents. Factors and multiples can be used to find relationships between numbers. How can we use a variety of models to understand rational numbers? How can operations with rational numbers help solve real world problems? How does comparing numbers describe their relationship? What is the relationship between fractions, decimals, and percents? How can number relationships help with problem solving? And so now we have to divide byġ,000 to get the right value.How do we work with rational numbers in real-world situations? We get the right product, we've got to shift Shift the decimal an aggregate to the right three times. Dividing by 100 andĭividing by 10- this essentially accounts for We re-expressed thisĪs 291 divided by 100. We wrote the expression, we had one, two, three total So if you divide by 1,000,ĭecimal in purple. So you divide by 10, divideīy 100, divide by 1,000. Dividing by 1,000 isĮquivalent to moving the decimal over three With 9,312- and let me throw a decimal there. Times 1 is 3, but notice, it's in the tens We already know how toĬompute this type of thing. To this product, I have to divide by 1,000. Quantities than this one is right over here. Notice, I've justĮssentially rewritten this without the decimals. To move the decimal so that when we divide by 1,000. Now, why is this interesting? Well, I already know how Over here, I could rewrite as dividing by 1,000. Then I divide by 10 again, I'm essentially I'm just reordering this-ĭivided by 100, divided by 10. Rewritten as- this is going to be equal to 291 Instead of writing 3.2, I could write 32 divided by 10. This interesting? Well, I could rewrite 2.91 timesģ.2 as being the same thing as. Never say that word- 3.2 can be rewritten. So it makes sense thatĢ.91 is the same thing as 291 divided by 100. Or if I take 200 and dividedīy 100, I would get 2. It also make sense, if I takeĢ, and I multiply it by 100, I'd get 200. The decimal place two places to the left- one, two. And we know that if youĭivide something by 100, you are going to move Think about it is 2.91 is the same thing asġ0, divided by 100.
