Today's math intervention game is: Fill 20
Materials: Game Board (click the picture to download a game board), number cube, counters
If your students are working on counting to 20, follow these directions:
1. Get a game board and bag of counters for you and a partner
2. Student 1 rolls the number cube and puts that many counters on the game board.
3. Student 1 tells partner how many counters are on the game board altogether.
4. Partners take turns
5. Players tell partners how many counters are on your game board after each time new counters are added.
6. The first player to fill a game board wins.
If your students are working on adding two groups of numbers that will have a sum less than 20, follow these directions:
1. Get a game board, bag of counters, and a cover (this could be a piece of cloth)
2. On the first turn, player 1 rolls the number cube and puts that many counters on the game board.
Player 1 tells the partner how many counters are on the game board and then cover the board.
3. Student 2 does the same.
4. On the next turn, player 1 rolls the number cube and makes a prediction on how many counters
will be on the board altogether when the rolled number of counters is added.
5. Take the cover off game board, put the counters on, and check the prediction.
6. Student 2 takes a turn
7. The first player to fill a game board wins!
If your student is working on subtracting within 20, then follow these directions:
*For this one you will need a number cube numbered (-2, -1, 0, +1, +2)
1. Get a game board and bag of counters for each player
2. Fill the game board with 20 counters.
3. Player 1 rolls the number cube.
4. Player 1 tells the partner how many counters will be on the board after player 1 either adds or
subtracts the number rolled.
5. Add or remove the amount of counters from the roll and see if the answer is correct.
6. Player 2 takes a turn.
7. The first player to empty a game board wins!

These recording sheets are the way I track student progress (with anecdotal notes). We do activities for structuring (making 5 or 10), addition and subtractions, numeral identification, and forward and backward number word sequence each week. I take formative assessment notes on each activity and corresponding day, so I remember how certain students do on certain days. This helps me to know if I need to keep with a certain activity, go back in the progression of skills, or if my students are ready to move on. This has been extremely helpful for me this year!
Remember to link up your fun math activities!!
