Title - 10 second math - addition/subtraction
By - Deb Lloyd
Primary Subject - Math
Secondary Subjects -
Grade Level - 3-4
This game is played with 3 players. Teacher preparation - The teacher provides a square piece of paper with 50 2cmx2cm blank boxes. The students fill in all the boxes with any numbers from 1-100. They cut out the boxes and place them in a container.
The first student has a calculator, the second has the container, a pencil and a scoring pad and the third student tries to work out the answer if two numbers drawn out were added together.
How to play - one student draws out two numbers from the container, one student works out the answer on a calculator and the last student has 10 seconds to mentally work out the answer. The student doing mental computations keeps having consecutive turns until she makes a mistake - play is then passed to the next student. For every correct answer the person scoring makes a tally mark. At the end of 10-15 minutes the student who has the most tally marks wins the game.
Variation - subtraction. The smallest number subtracted from the largest number.
