Math Operations Activities for 2nd Grade

A few weeks ago, we did some math operating in our homeschool 2nd grade math class!
🙂

And, ya’ll, I wish we had worked on this much sooner!  My kid is a strong
math thinker, who struggles with notation or showing/telling me how he figured
out his answer.  His little brain works so fast that he has a hard time
using the right language to explain his thinking.  That has been my main
goal this year for him.  

I knew it was important for him to know and understand the 4 math operations,
but I had no idea just HOW helpful it would be in giving him more math
language to frame his thinking and ultimately write down his notation in a
mathematical way.  

Sound familiar?  Here’s a look at our week of
math operations!

Introducing Math Operations

We kicked off the week introducing math operations.  I wrote the numbers
6 and 2 on the board and asked, “6 and 2 come to our math hospital. 
There are 4 math operations that we can do with these numbers.  What’s
one thing we can do to 6 and 2?”

As we listed out the operations, we
charted
them.  We charted the symbol, the name of the operation, the sample
equation, and keywords or phrases we use when performing that operation.

Once we worked through all 4 operations and compared and contrasted them, we
read the digital book from my
Guided Math Workshop Plans
called, “Socks for Knox.”

Each page has a different story problem type.  We read the problem and
discussed which operation we should use and why.  The answer is less
important…in fact, that’s why I used very low numbers.  I wanted him to
think about the operation and not get caught up in the numbers.

Let’s just take a moment to add that I really, *really*, wanted my 2nd grader
to dress up in his old doctor outfits and pretend like we were performing
surgery, but he wasn’t having it.  #boys  This would make a super
fun classroom transformation project though! 🙂

Math Operations Sort

In
Guided Math Workshop, Mondays are mostly whole group days where most of the content is
frontloaded and introduced.  Then, the rest of the week, kids work independently on the goals and content we learned on Monday.  They
solve a new problem independently each day, play a hands on game with a
partner, meet with a teacher in a small group to discuss their problem solving and work on a technology based game to practice the math skill
from Monday.  You can read more about those routines here.

This week, our hands-on activity was an operations sort! We used the cards
to sort symbols, equations, and stories into the 4 operation categories.

These
cards
can also be used to play memory!

Then, he did a
cut and paste sort on his own.

All of this practice made a HUGE difference in his ability to show his
strategies during problem-solving.  He was able to name the operation
he needed to use and write his equation more easily.
