What a FANTASTIC day I had!!! Today I introduced integers. I have done videos over how I teach adding and subtracting integers. This post is about how I introduced integers to my students today. Believe me when I say that my students left my class with a smile on their face and a love for math.
I used the beginning part of my “adding integer freebie” that I provided in the post with the adding integer video. I’ll put the freebie on this post as well. I began by having my students get out their spiral notebooks (math journals). I didn’t really feel like the things I wanted them to jot down were really conducive to making a foldable (maybe I’m wrong and you can tell me a better way). I just had them copy the vocab definitions and I explained them as we went. The heading was to be written “Integers” underneath that they listed out the vocab and definition.
integers: all positive and negative whole numbers
positive number: all numbers to the right of zero on the number line
negative number: all numbers to the left of zero on the number line
I then followed the beginning of the freebie packet. I went through it, having the students write the information down as I wrote it on the board. I had the students answer the problems as the packet does. I have over 100 students, and administration that is on us for making too many copies. If not for this, I would have printed out copies of the first two pages of the packet and would have gone over it step-by-step instead.
Prior to class, I had printed out, laminated, and cut out the integer cards in the freebie packet. I gave each student one of the cards and asked them to number themselves from least to greatest. After they ordered themselves, I had went down the line and the students said “yes” or “no” as to whether that person was in the correct spot (they were all correct in all classes). In each class, I said a “wrong” answer just to see if they were paying attention. While the students still had their cards, I told them to “travel” until I counted down from five. After allowing them to walk around the room for a little bit, I counted down from five. After I said “one”, they were to find a partner that was next to them. I told them that the partner with the card of the greatest value between the pair was to raise it up in the air (I didn’t really go through and check each answer. By this time, they had the hang of it.) We did this a couple of times with the greatest value and we did it a couple of times with the lowest value. The students then returned the cards to me.
I then had the students partner up and turn their chairs to face each other. I gave them the “Whack-a-Mole” cards that I have for sale here in my blog or in my Teachers Pay Teachers store for $2.50. The cards have integers on them, and is played in the same fashion as the card game “Slap Jack” except that the students are to “whack” (slap) the card with the greatest value. I did explain to them with great emphasis that they were not to try to injure their opponent. I told them that they would forfeit their game playing time if they did act appropriately during the game. My students LOVED the game, and I mean LOVED it! If you ever want to know how to get an unmotivated student motivated, make the lesson a game. Below is a freebie download (it’s the same as the adding integers freebie) as well as a link to buy the “Whack-a-Mole” game. The graphics on the “Whack-a-Mole” game are so super cute. If you don’t have to make many copies, or you just want to make them special you can print them out in color. We are changing to Common Core next year and I won’t be teaching integers next year, so I just printed them in black and white and didn’t laminate them. Either way, they are super cute!
