What can you do with a card set of numbers 0-10? Maybe more than you can possibly imagine for good, simple math fun! They can be used for addition, subtraction, comparing numbers, even/odd practice, place value and more!
Often, there are learning activities that we do in school during the day that can't be sent home. I'm really glad that you have stopped by so I could share this one with you!
I made a set of number cards for each of the students to use for various math activities and partner games. I like them better than a deck of playing cards sometimes because we don't have as many face to cards to take out and sometimes you just need a ZERO!
Cards in Action
Each child has their own set of cards to manipulate and use for practice activities and partner games. They are stored in these library pockets.
Some activities start with a shuffled deck turned upside down in a draw pile.
First, we lined them up all of the cards in order from greatest to least and then turned over some to show only odd numbers. This was skip counting by two backward practice as well and helped with instant recognition of odd numbers through 10.
Next, the students had to show a two-digit number that was even.
The cards went back into a pile and then they were asked to flip up three cards. The task was to show the greatest number with those cards. It got tricky when those zeros turned up. Zero is not nothing! Zero is something!
Elbow partners had to work together and compare numbers to see who made the largest.
When a ten was turned up, it lead to some great discussion regarding place value to the thousands place.
Hmmm...what to do with that zero?
The rule was set that it can't be taken away.
Yes, that works!
Next, four cards had to be turned up. The students could create a double digit addition problem of their choice and record it and solve it in their math notebook. Next, they were asked to rearrange some or all of the cards to create a different problem in which the sum remained the same (most saw that it could be the turn-around), and again in a way that would result in a different sum.
The next challenge was just that, but it was such a great one for getting the kiddos really thinking.
I called out a direction to create a two-digit subtraction problem where regrouping would be necessary. This is a new concept that was only recently introduced.
One student showed this problem. They were on the right track with the digits in the ones place but failed to look at the entire problem. This was a great opportunity for questioning.
This student got it right away!
Another student made a model using his pencils to help himself to better see tens and ones in columns as he had seen on many practice papers. Because he had trouble with the concept of regrouping, I was able to pull out another card from my teaching set of extras to use as an overlay to demonstrate what we had done days prior when we decomposed cubes stacked in towers of ten.
I cannot wait to get the cards out again!
The students love all card and dice activities
and so do I!
In just 15 minutes, we had a wonderful math review and I learned so much about the students and where they each were in their mathematical thinking and skill.
Number Talks
We also started official number talks this month, although we have been doing them informally all year as part of our math block.
First, the class set some important rules for math talk time.
In our very first practice number talk, the students were shown three cards. I asked the question, "What can we do with these three numbers?"
The teacher records student responses as we come up with different approaches to problem-solving. These are just a few responses from the class. Adding student names encourages greater participation and allows us to refer back to an idea and have the child expand on it if necessary.
There are many different strategies that can be applied to any problem as you know from completing the homework assignments when asked to explain math reasoning using words, numbers and pictures! The idea is to use mental math over other strategies as often as possible.
The goal of using number talks in our classroom is to improve upon computational fluency, explore new ways of thinking about math and develop sound mental math strategies.
Parents, MAP testing in reading and math begins next week! Using Dreambox at home is a great way to review many math skills!
