If it is a constant, we call it dollars. So, 3a + 5b + 4 would be apples, bloodhound and dollars. If they try to given me 8ab, I tell them to picture what a cross between a bloodhound and apple would look like. If they are categorizing them in the room, they would be in 3 different pilesUnknownhttps://www.blogger.com/profile/02059651815760204160noreply@blogger.comtag:blogger.com,1999:blog-1542724471702676307.post-77918642328299401052012-10-25T22:29:52.535-04:002012-10-25T22:29:52.535-04:00LOL...I use cats and garbage trucks.

No one else has pointed out a possible "why" in the comments to explain the amount of unintended group-think on this one. So I'll assume the reason why I teach it this way applies to everyone ... we all grew up hearing the saying "comparing apples to oranges" which obviously puts us in a fruit mindset when combining like and unlike termsAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-1542724471702676307.post-10151515672871737652012-05-04T17:46:32.512-04:002012-05-04T17:46:32.512-04:00Wow.

This was something that always just made sense to me in math class, and my first year or two I couldn't understand why my kids just didn't get it. Through some trial and error I found that naming it "The Banana Rule" and referring to it vs. just telling them it's like adding fruit seems to help it stay memorable for longer.<br /><br />Finally, after going through this a couple times with my class this year we started referring to adding unlike terms as "Making fruit salad" which is pretty fun.<br /><br />Thanks for the comments!Mr. Sweeneyhttps://www.blogger.com/profile/09576574228194571537noreply@blogger.comtag:blogger.com,1999:blog-1542724471702676307.post-89155314667683017102010-04-24T14:50:12.562-04:002010-04-24T14:50:12.562-04:00I use this too, but I don't always use bananas...I use this too, but I don't always use bananas.

This one says, focus on the fact that you have 1 of these monsters and 3 more of the <b>same kind</b> of monsters, so there's 4 of these monsters. (I like monsters, because it looks like a scary monster to the students.)<br /><br />The rainbow seems to me to just be a memory trick. Could be useful, but I'm guessing there's a way to work with those problems that helps students see why they work the way they do.Sue VanHattumhttps://www.blogger.com/profile/10237941346154683902noreply@blogger.comtag:blogger.com,1999:blog-1542724471702676307.post-74125116262842049682010-04-24T00:36:26.615-04:002010-04-24T00:36:26.615-04:00I use the apples too, maybe from seeing the others...I use the apples too, maybe from seeing the others mentioned? My students will mess with the exponents too. I get specific with my fruits by saying "If we have green apples and red apples in a basket and I tell you to find the number of green apples, do you count all the apples?" That always helps them until they forget two days later. Hopefully it sticks with a few of them though.Craighttps://www.blogger.com/profile/17953641387474397371noreply@blogger.comtag:blogger.com,1999:blog-1542724471702676307.post-38960972690749287622010-04-23T20:04:44.009-04:002010-04-23T20:04:44.009-04:00I can definitely use a simplified version of this ...I can definitely use a simplified version of this in my 8th grade math class right now.
