SUBTRACTING INTEGERS PRACTICE

In our notebooks we first made sure we could generalize the real rules for adding integers. Then students took turns creating an integer subtraction problem. We then discussed all the possible options for answers.

I shared a major math moment with the class as I remembered learning this when I was in 7th grade and subtracting integers was a devastating moment for me. I remember the confusion and the discomfort. Most of all I remember the help I got from my teacher. So I shared a major hint that he shared with me.

"ADD THE OPPOSITE"

When subtracting integers change the subtraction (-) sign to (+) and then change the 2nd integer to its opposite. At that point you can follow the addition rules for integers.

ADDING & SUBTRACTING DECIMALS WHEEL DECIDE

In class today we spun the wheel to create our practice problems.

DECIMALS MEET INTEGER RULES = WHOA!!!!!!

We are combining our knowledge of integers and decimals and it is proving to me quite a challenge. To continue working on this skill we worked on a Halloween themed coloring sheet with about 18 problems. Below is the “cheat sheet” I posted for the class about integer rules. We will continue working on this skill for the remainder of the week.

PRODIGY ASSIGNMENT

Students have an assignment to begin that combines their knowledge of integer rules and decimals. At first I know they will be less than excited but I have faith they'll do fine. All students know their Prodigy log ins, they should be written in their agendas. However, if they get home without it, please feel free to email me and I can get you that information quickly.
