Title – Bingo Blitz
By – Abbie Artley
Subject – Math
Grade Level – 3-4
Overview: Students will do math problems and find answers on their bingo cards. I use this game for decimal computation, but it can be used for just about anything!
Objective: Bingo Blitz is a fun way to review a variety of math concepts.
*Bingo Cards and Answer List (directions for making are below)
*Beans (or other items to use for markers)
*Pencils (one for each student)
*Overhead projector or chalkboard
Bingo Blitz can be used in many areas of mathematics. I use it to sharpen my students’ decimal addition and subtraction skills. The following instructions are based on this concept, but it can easily be adapted for many different math ideas.
Instructions for making Bingo Cards and Answer List:
1. Draw a grid consisting of 25 squares. The squares need to be big enough for the students to write decimal numbers. You can fit 4 grids on one sheet of paper, or you can draw two grids and leave some room for students to work out the problems.
2. Develop about 50 decimal sum and difference problems. You can find these in workbooks and textbooks, or you can make up your own! Write the answers on an overhead transparency. The students will copy answers randomly on their bingo cards. Write or type the problems AND ANSWERS on paper and cut the problems apart. Put the problems in a paper bag or hat.
3. Pass out bingo cards and beans to each student. One handful of beans is plenty! Make sure students have a writing utensil.
4. Put the answer list on the overhead projector or write the answers on the chalkboard. Have students RANDOMLY write answers in squares on their boards. Do one board at a time. You can use the same board over and over or copy new numbers for each game.
5. Pull out a problem from the bag or hat and write it on the overhead or chalkboard. Students will use scratch paper (or their bingo cards) to work the problem. If the answer they get is on their card, they get to put a bean on that square.
Note: You may set a time limit or have them use mental math. these details are up to the individual teacher.
6. When a student has a bingo, have him/her read the answers, and you can check for accuracy.
There are many ways in which teachers can use this game: vocabulary review, geometry concepts, basic computation facts, and even algebra and calculus! That’s why I love using this game- it’s very versatile.
