Bingo For Numbers 21 – 50

Everything Early ChildhoodMy four year old loves Batman, Paw Patrol, Karate, and bike riding. He is a sweet, tenderhearted little guy, and like most four year old boys would rather be up playing than sitting. He learns totally different than his mathematical and analytical minded 18 month older brother. I have to be intentional about making learning fun, and include lots of repetition.

Mathematically, this little guy has mastered his number to 20. We have played with base ten blocks, done ten frames over and over with do a dot markers, and have even played with tally marks as we did a shape hunt in the grocery store. Now I feel like we are ready to move on to higher numbers. It seems so easy to find activities for numbers 1 – 20. After that they are fewer and far between, though This Reading Mama has created some great number cards that explore many numbers past 20. I also just found a cool memory game by Playdough to Plato using base ten blocks.

Knowing C’s need for repetition I decided to create a game and activity that would allow him to continue his work with higher numbers and still use the base ten blocks and ten frames he was accustomed too.

We started off working on the numbers 21 – 30. To begin, I had him make each number with the base ten blocks, and then the ten frames. I simply wrote a number on a white board and he filled up my quickly drawn ten frame with game markers, and then laid out the correct amount of base ten blocks.


The next day we made Caterpillars. Since it is finally spring, I decided caterpillars were the perfect animal to create. I laid out the face and the numeric numbers for him. He finished the caterpillar with the correct tally mark, base ten blocks, and ten frames. We had out our hundreds chart out because he often has trouble counting on. We have sung songs with skip counting so often he can count by 5’s and 10’s almost without thinking. He struggles with remembering to stop counting by 10’s when he reaches 20 and then say 21. Having the number chart right there helps him remember how to count by ones when he reaches 20 or 25.


After creating the Caterpillars, we moved onto a game of BINGO. Both my boys love this game, so I often turn to it as a way for extra practice and fun learning. To save ink, we used the models from the caterpillar as the game pieces, and had a blast as we worked through the numbers 21 – 30.

I decided to set this game of BINGO up a little different. In a normal game the caller will pull a card, call out the number, and then everyone will cover the same number. It would be difficult for little ones to have a whole bunch of tally marks, base ten blocks, and ten frames on a card and have them figure out what they represent over and over. Instead the numbers are on the BINGO cards, with the models on the drawing cards. Since it doesn’t do anyone any good if you figure out what the model represent this is what I recommend.

Start by pulling a small group. (I pretty much recommend you teach math in small group at all times, which isn’t hard if you are a homeschool mom. It does though require a little more planning if you are in a classroom with 25+ kiddos.) Once you are in a small group, pass out the BINGO cards and place markers. Then give each student a card with the models on it. All the children can work on figuring out their model at the same time. Once they give you a correct response, they may cover up the corresponding number. After everyone gives an answer, pass out a fresh batch of models. The first person that gets five in a row or fills the whole board wins.

Enjoy this fun time of learning with your kiddos!!!!
