Integer Rules Why?

 

During the month of February, we started reviewing for our State test.  As we learned new concepts and reviewed previous ones we looked at why the rules work and how did they work. This took time, it time that many may say was a waste or could have been used elsewhere.   

For struggling students or students who aren't great at memorizing this is very helpful. I find that in math students are told this is the rule and you need to learn it.  The reason behind the rule isn't explained or shown.  I've been challenging my students to ask questions, seek to know how or why it works, and not just believe something is true because I said it was.  

This had led to great discussions.  For example, why does minus a negative change to a plus sign.  You've probably heard two negatives make a positive but why does it work.  We spent a day looking at why the integer rules work.  If they know the reason behind it, it helps as they are working out a problem or building on this skill.  

Take a minute and think about how you would solve this equation.

4x + 1 = 3x - 2

I would move the 3x first but it's not the only correct first step.  Solving an equation is a great way to discuss multiple paths to the same answer.  We looked at how we could solve it and some students move x left and other move it right.  You can discuss does it matter which side x is on.  

If your students are struggling, I would encourage you to look at the foundational skill you are building on.  I'm finding that if I spend a little extra time on a foundational or prerequisite skill it makes the new skill easier to learn.

Baby Yoda Pixel Art Template

  This template is set for 3 sets of answers.  I have the answers that are currently set, you will need to reformat them to use with your content.   Baby Yoda Pixel Art Template Be on the lookout for this activity given 2 ordered pairs and asking for slope, y-intercept, and the equation of a line.  I'm also formatting this for converting between percents, decimals, and fractions.  If you want to reformat it before I post the above activities here is how. 

Blooket Game

  A week ago my students kept asking to play Blooket so I looked into it.  Blooket is much like Kahoot and Gimkit but they earn money.  Blooket has several different game modes and the students LOVE IT.  Once a student has been eliminated they will keep playing to earn more gold which they can use to buy rare items.  Each week Blooket has a theme and those rare items can be bought for the week and then they are gone; the items include accessories or special characters they can play as.  My students will play for hours if we let them.  When we finish a game they are ready for another round.  Blooket has a FREE version which has been enough for my class but you can also upgrade to a paid version.  They have games that are already made or you can create a new game.   My students love the battle royale mode and the gold quest the best.  If you haven't given it a try I would highly suggest it.  

Long Division in Google Docs

  I was making a long division worksheet for my students in Google Docs when I realized that it wasn't under equations. Here's how to insert it.  This does not look very pretty so I have another video on how I do it in Google Sheets which takes longer but looks nicer.
