Tuesday 9/29 change

The eighth grade had a somewhat spur of the moment field trip to TJ high school which I conscripted to chapatonr since no one else would go. We were supposed get back in time for my 7 th grade class which didn't happen. The class spent the period working on the unit project. There is NO ACE due tomorrow as a result. Enjoy. We will do inv 2.3 in class tomorrow.

Investigation 4.3

Ok,  this investigation is asking you to put everything in the book together. It also is trying to have a context in everyday life where you might use the distributive property. The question about writing an equation for the cost of water and trail mix is probably the most instructive for this. 

Be careful when writing your equation to include tax. If tax is 4% and you multiply the cost by 0.04 do you get an answer that includes the items and the tax?  If not how can you write the equation so that one equation will compute the final cost quickly and easily?

 

Spoiler alert!  Don't look further until you try it...

If you multiply the cost of water and trail mix (1.50+2.whatever) by 1.04. The .04 is obvious, but the 1 represents the initial cost of the items. 

There are a bunch of questions that I don't love like the how do the order of operations...  Don't worry to much about these questions. 

Today we are doing a kahoot to review he book. I will post the name of it so that you can play it on Monday and then take a photo of your results and sent it to me. Enjoy CA.

AN Investigation 3.4 Launch

This investigation is a chance to get a bunch of practice using your x and / algorithms in a fun way.  Here's a quick video of how to play, please pay close attention to the end of the game.



There will not be an additional video because the purpose of todays class is to practice multiplication of integers.
