Grade Level:



 The Lunch Lady game will give students practice with calculating prices by adding decimals.  Students will be able to correctly solve multi-digit addition problems involving decimals.

Common Core Standards:



Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.


Fluently add and subtract multi-digit whole numbers using the standard algorithm


Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.


Warm-Up Activity:

Watch a short adding decimals math video as a way to engage your students and review the mathematical process of adding decimals prior to playing the “Lunch Lady” game. The adding decimals video can be accessed at the followed link.

Warm-Up Activity #2:

Another good warm-up activity prior to playing this game is to use the an interactive math workshop available on this site called – “Decimal Workshop”. In order to locate the interactive decimal workshop, go to the following link and select adding decimal. ¬†–
This activity could be done as a whole activity by allowing the students to work the problems out on dry erase boards. Then, the teacher can quickly identify which students are ready to play the game and which students might need extra practice adding decimals. The decimal workshop could also be used as an independent warm-up on individual student computers prior to playing the “Lunch Lady” game.

Main Activity:

Now that your students have reviewed adding decimals they are ready to play the “Lunch Lady” game. Have then watch the instructional video at prior to playing. This game could be played in a variety of ways. If you have lower level students that might need help, simply pair them with a higher level student in a computer lab situation. If you want to play the game as a whole class activity, ask all students to work each problem. Then, let them know that you will be randomly calling on students to answer. This will help to hold each student accountable, during a whole class version of this activity.
