hey guys, So today we were leaning about balancing algebraic equations. One example was 3b+ 1=2b+7. Using a scale you would figure out what b is. To write this equation out and figure the out you need to break it down by subtracting first. It we take away 1 it would work out to be 3b-1=2b-1 which would then equal 3b=2b+6 and trying to figure out how to isolate b. next we would take away 2 bags to get 1b=6. This would let us know that for every bag you need 6 blocks. Then we can plug in 6 for the b so the equation would now be 3(b+1)=2(6)+7. Zahabi, N. Oct. 27th 2017. "Balancing equations." Retrieved from my own library. The activity I was given was brought up by Nadine. She also talked about balancing algebraic equations to make the expressions true. We used a scale to figure out what the missing numbers were (the sheet of examples is below). She set out rules that [] and delta can not equal 0 so there had to be a number on both sides that were greater than 0. Whe

Hey guys, So today we did an awesome game on proportional thinking. It was called crack the ratio code by Stephanie Hicks. The goal is to find the missing factors in equivalent rations. If the ratio is 1/6 = 3/a then we need to find what a equals. To figure this out we need to figure out how many times the first top number goes into the second top number so this case how many times 1 goes into 3 which is 3. This would then let us know that we need to multiply the bottom letter by the number on the bottom. So 6 times 3 would be 18 so A would be 18. The end goal would be to find what each letter equals in order to get a phrase at the end of the page. So the end phrase in this case was math is fun, as pictured below. There are few others way we could change this up to be different depending on the class. Every student could get a different phrase that they have to decode in order to make sure that no student is cheating and copying off each other even if they don't understand it. Th

Hey guys, So integers are of one those things that students and even adults can struggle with. Whether you're learning about them for the first time for basic math or you're using them as an adult to understand your debt you use integers more than you think. Who said though that integers can't be fun. In our math class we learned how to play with integers as we learned how to use them. By using manipulatives such as army men or balls or cards you can give kids a hands on experience of how to learn integers. In one of our examples they used army men. They used two different colours in which the dark green ones were positive and the light green ones were negative. By playing a game to understand addition with integers we can see how negative numbers can lead us to positive numbers and vice versa. If we used the army men to go to battle they would have light green vs dark green. Using the question such as -2+3 you would take away two light green army men to battle two dark g
