I know that six plus one is seven.

Really, I do.

And I am sure that re-posting information from an earlier post is expressly forbidden in the Blog Rules of The Universe.

However,
I am also thinking there is a caveat somewhere that says: If your
picture--in a post about algebra--suggests that six plus one is eight,
you have an exemption...

And you are allowed, actually

*encouraged, *to post a fix-up!

I
have been fretting about my algebra post for a while. Most of my posts
don't get a lot of views, and I used to just move on to creating the
next installment, hoping that someone would find something they liked or
could use.

And then Pinterest hit the scene!

Of
all the things I have posted on my blog, only a few have achieved
multiple pinnage: my TBA freebie, my desktop organizer, and the
"Connections" anchor charts.

Oh.

And an algebra activity.

An algebra activity where 6 + 1= 8!!!

Apparently I took the picture after a child arranged the "like terms"... and then I never looked at the answer.

A very nice "Anonymous" commenter wrote: "Shouldn't the constant be 7 (not 8) in your photo example?"

In other words, "Hey, BlogGirl! 6 + 1 is not now and never will be 8!"

So
I am re-sharing bits and pieces of the old post... with added details and some differentiation in case
you have students with varying needs in your math class or group.

Details
on playing or reviewing are detailed below! And you will notice that 6
+ 1 is now (happily) 7! How long do you think it will it take for me to
contact all those friends who pinned the picture with the incorrect
answer...

__Algebra Deja Vu, Take 2__
If
you're like me, money is short and time is limited. Still, you

*want *to
provide opportunities for math instruction (and interaction) that are
beyond paper-and-pencil.

If you are REALLY like me, you just want another
excuse to cut up colored cardstock on your 1993 vintage paper cutter! (Aren't you glad you're NOT like me?)

Here's
a quick game that helps kids practice combining like terms.

I always like to
do a few games like this early in the school year. Afterwards, the sixth graders
often ask, "When can we do algebra again? Algebra is fun!" Isn't that
music to a teacher's ears!

Here are the cards you will need for this activity. Click on the picture to take you to the Google.docs document.

Sometimes
I have the kids roll an 8-sided dice to determine how many cards they
will use (Rolling a 1 or 1 2 is an automatic Roll Again)

So a card selection might look like this:

Need to differentiate?

Start with only the cards that have positive terms and integers (then the problem will only involve addition)

Need to differentiate further?

Limit the choices to one variable and the unit cards

If
you have children who have some academic/mathematic struggles, there
are still ways of adapting the materials so that these students are
playing right alongside their peers. For example,
the students can use cards with only whole numbers (no
variables). Manipulatives can also be added to support students working
with whole number cards--or even a calculator.

To
adjust the activity to include a peer with more significant needs, a
set of cards with dots or squares can be prepared. so that a student
with special needs can still play along--with adapted materials.

Even these cards can have varying levels of difficulty--shapes in a row are easier to count than shapes not in a row.

I posted the page on google.docs in editable format (I
think), so you can make the cards easier or more difficult to suit the
needs of your kiddos.

You can have students work in a
center or work on their own as part of practice and review with a
circulating adult. In this case, students need their own materials.

If you have one of those
"Can-I-Help-You?" Pals with scissors and a smile, you can get out of
cutting too! (I, of course, have offered to cut the pieces for

*other *classes! Crazy, I know!)

I am more inclined to have students work cooperatively in partnerships.

Just run
off enough pages on cardstock to have a set for each two or three
kids. (I've never tried it with four... but if they can collaborate
and cooperate, good on you!). You may want to run off more than one page of cards to increase choices.

The
outcome of the activity looks like this. The students has drawn cards,
written an expression with the like terms together, and then combined
like terms in an expression.

Interactive play is summarized below:

I'll
speak of twosomes because some of my kids are still at the "learning
to survive in a partnership" stage. We've done the conceptual part of
the learning and a funny intro with cotton balls (Ahhh... material for
another post!), so this is just a warm-up/practice. I usually have
kids work on whiteboards, but paper folded into eight squares would
work fine too.

Each player chooses two cards
initially. They work together to combine like terms, discussing
putting the variables in alpha order with units at the end of the
expression. I usually have to remind them that this is not an
equation; we're not solving, just practicing combining the terms. They
talk about it and write the expression on the white boards. This is,
obviously a precursor to solving equations, we're just not there yet.

After
they have chatted about several combinations, I ask each partner to
choose three cards--making a total of six. If you're brave and they're
ready, you can have them play "Write. Share. Compare"

After
looking at the cards, each partner writes the expression. They count
"1-2-3- Share" and then compare. If there is a discrepancy, they talk
it through. I love to hear: "Oooooh. I get it now!"

I hope that someone can adapt this activity for her/his class. And I hope you'll let me know if it works for you.

Mostly I hope that your students will have fun!
