This model allows us to add using our counting (or natural) numbers to compute multiplication problems easier.  This can also be used with negative numbers. You just have to use the "face rule." For example, a positive and a negative numbers means we are sad (negative outcome). ]]> 2017-11-13 19:29:35 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206447685 elizabeth_h13 https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206450322 With this model, we are able to visually see what we are adding by using "chips" (circles). We just have to remember to keep the sign we are given in the equation. (There are examples below to explain.)]]> 2017-11-13 19:33:26 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206450322 elizabeth_h13 https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206451574 With subtraction, we need to remember our K-F-C rule to be able to draw our model. This model is similar to the one we used for addition. We are colored coded the types of numbers (positive numbers are blue and negative number are red). This allows us to visually see how subtraction occurs. ]]> 2017-11-13 19:35:17 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206451574 elizabeth_h13 https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206465184 This is a visual model for dividing integers. We will be able to see how the total number (the first number) divided into equal groups (how many in a group is decided by the second number). The outcome (quotient) will be how many groups there are. For this example, I used positive numbers but you can also use negative numbers now. You just have to remember the rules such as two negatives in a division problem makes a positive quotient. ]]> 2017-11-13 20:00:28 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206465184 elizabeth_h13 https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206480071 7.3 The student will

I will go through a few examples, but there are many other ways to show operations of integers. ]]> 2017-11-13 20:57:31 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206489436 elizabeth_h13 https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206489980
 This is an example of using number lines for all of the operations of integers. The example here is using all positive numbers, but we can also relate it to the negative integers, as well. ]]> 2017-11-13 20:59:02 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206489980 elizabeth_h13 https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206492659 The number line model for multiplication allows students to see the grouping that happens because of the "hops." You can also use this for negative numbers, just like all of the other models for the operations of integers. ]]> 2017-11-13 21:06:54 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206492659 elizabeth_h13 https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206493229 This is a way to not only learn about number line subtraction, but also view place value (which they should have learned in elementary school). ]]> 2017-11-13 21:08:33 UTC https://padlet.com/elizabeth_h13/6j9wych9t4h1/wish/206493229
