Let us consider float division first. We consider those in the next section.
Friday, September 7, Teaching the Distributive Property After having to reteach my Algebra 2 students the distributive property, I wanted to make sure my Algebra 1 students had a strong understanding of the distributive property. Looking online for ideas, I found the idea of teaching the distributive property using combo meals.
I cut them out and laminated them. Then, I glued magnets to the back. If you're wondering why I included apples and bananas with my fast food, well I can tell you it's not because I'm crazy.
Instead, I wanted to use these again whenever I teach combining like terms using the banana rule for combining like terms.
I started off by asking students what the cheapest way to get a burger, fries, and a drink were at a fast food restaurant. I hoped they would suggest a combo meal. While each class eventually did suggest that, many students instantly replied "The Dollar Menu.
We discussed how to write each combo meal as an algebraic expression. Of course, the students had to criticize my choices of foods for the combo meals. Apparently fritos are gross.
And, I've learned that nobody in their right mind would drink diet dr. Distributive Property Using the Concept of a Combo Meal I think my students thought that by making magnets of a certain food I was somehow endorsing it.
Honestly, I don't drink pop at all. I only picked Diet Dr. Pepper because it wouldn't use as much printer ink as other brands would. And, on top of that, I'm a vegetarian.
So, I don't eat hamburgers or hot dogs. When we talked about how many hamburgers we would get if you ordered 5 combo meals, the students knew the answer straight away.
When we moved onto problems that didn't involve food, things didn't go as well as I thought they should have. Students could see why we would multiply everything in the combo meal by the number outside of the parentheses.
But, one student wanted to argue that since there was only 1 number outside of the parentheses, we could only multiply one of the terms inside of the parentheses by that number.
I had students create a foldable with the four different variations of the distributive property. I left my interactive notebook at school, so I don't have a picture of it at the moment.Piecewise Functions A Function Can be in Pieces.
We can create functions that behave differently based on the input (x) value. A function made up of 3 pieces. Valid Item and Component Labels ESEL,Type,Item,Comp,VMIN,VMAX,VINC,KABS.
Comp. Description. ELEM Element number. ADJ Elements adjacent to element VMIN (VMAX and VINC fields are ignored).
Only elements (of the same dimensionality) adjacent to lateral faces are considered. ABSOLUTE VALUE AND PIECEWISE FUNCTIONS In order to remove the absolute value sign from a function you must: 1.
Find the zeroes of the expression inside of the absolute value. 2. Make sign chart of the expression inside the absolute value. Write as a piecewise function. Be sure to change the signs of each term for any part of. continuous. Then, evaluate the graph at any specified domain value. You may use your calculators to help you graph, but you must sketch it carefully on the grid!
