'Addition & Subtraction Game' - A Facts Below 20 Game - Think & Cover is a strategic thinking game used to practice Addition and Subtraction number facts below 20.

Here is a Video of How To Play
How to Play 'Think & Cover'

What You Need:

2 players
1 Think and Cover game board
20 red transparent counters
20 green transparent counters

How to Play:

1. Player 1 chooses 2 uncovered numbers and either ADDs these numbers together or SUBTRACTs the smallest from the largest. Player 1 then places a blue counter on the numbers they chose and a red counter on the answer to the algorithm.

Teaching Points:

- Have student say the full algorithm as they cover the numbers to add an extra layer of learning.
- Have opponents mentally check the algorithm to ensure accuracy.

2. Player 2 removes the red counter & places their own blue counter on that number and a blue count of on another uncovered number. They then either add or subtract the numbers and place a red counter on the sum or the difference.

3. Play continues in this fashion until no numbers can be covered.

How to Win:

The player who leaves the other player no options to cover is declared the winner.

Professional Reading:

- If you are not aware of the work of the Stanford professor Jo Boaler take the time to read her thoughts.
- Do some research on Number Talks.

Before the Game:

- Number Talks
- Introduce the word 'thwart'.
- In this type of game one of the best pieces of advice I can give you is to plan ahead in order to thwart your opponent.

During the Game:

Have you found any ways to 'plan ahead' to help you win the game. Tell me about it.

Possible Journal Reflections:

- What strategies did you experiment with to win this game?
- What do you know now you didn't know before the game?
- What do you think the quote on the game board, 'Effort is the road to mastery' means?
- A person is either born a 'Math' person or not. True or False? Explain your answer.
- Many Math professors now believe intelligence and ability in Math grows with thinking and effort. What is your opinion on this?
- What does 'growth mindset' mean to you?
- If 'Math is the science of patterns', what number patterns did you use today?
- Have one student dictate their answer while the other player records their answer.
- Why do you think the author of this game has called it ‘Think & Cover’?
