Unit 3

Ready-to-Use IM Aligned Fluency Practice 

Fluency Objective: Partitions of Ten and 100

Game: Making 100

Concepts covered: 

• Adding and subtracting multiples of 10

In this game, you use the numbers on passing license plates to practice addition. 

How to play:

1. Set a target number, such as 100.

2. Each player takes turns adding multiples of 10 to their running total.

3. When a car passes, the player whose turn it is looks at the license plate numbers. They can add any single-digit number on the plate and multiply it by 10. For example, a plate with "3B9" could be used to add 30 or 90 to their total.

4. The first player to reach 100 wins.

Fluency Objective: Adding Tens, Adding Ones

Game: 5 Moves to 100

Concepts covered: 

• Adding a multiple of 10 or a single digit to a running total.

Equipment: 6 sided die, paper, pen/pencil

5 Moves to 100

Fluency Objective: Mentally Adding to 100

Game: 100 Laughs

Concepts covered: 

• Creating two 2-digit numbers that add up to 100

Equipment: deck of cards with the Jacks, Jokers, and Kings removed (aces represent ones and queens represent zeros)

100 Laughs

Unit 4

Ready-to-Use IM Aligned Fluency Practice 

Fluency Objective: Counting Forward and Backward by Ten

Car Counting:

Concepts covered: 

• Adding and Subtracting Ten or Multiples of Ten

Practice counting forward and backward by ten starting at any number between 1 and 100.

How to play:

1. Choose a number between 1 and 10. 

2. Starting on that number, count up by tens.  (i.e. 7, 17, 27, 37, 47…)

3. Reverse direction when you reach 100 and count down from the current number by tens (i.e. 107, 97, 87…) Once you get back to the single digit number begin counting forward by tens again or choose a different starting number between 1 and 10.

Variations:

• Reverse the counting direction every time the driver breaks for traffic.

• Determine a multiple of ten to count by.  (i.e. count by 20s 7, 27, 47, 67… or count by 30s 7, 37, 67)

• Extend the counting past 100.

Fluency Objective: Adding and Subtracting within 100

Game: Add and Compare (or Subtract and Compare)

Concepts covered: 

• Adding (or subtracting) two numbers within 100

Equipment: 

• Deck of cards with digits 1-9 (Use Ace cards as 1 if using playing cards)

How to play:

1.        Each player draws 4 cards from the pile.

2.       Both players use their cards to make two 2-digit numbers and add them to find the total.

3.       The player with the greatest total collects all 8 cards and play resumes with the next round.

If playing to practice subtraction, the players subtract their two numbers and the player with the smallest difference collects the 8 cards.

The game is over when one player runs out of cards.
