## Another Energizer for Number Flexibility

This energizer is called Rule of the Day.  The teacher states a rule like:

Doubles,

Doubles Plus 1

Half Facts

Ten More

Ten Less

Multiples

Then the game begins.  The teacher says a number and the students have to answer following the rule.  For example, if the teacher said, the rule is “Half Facts” the starter number is 20 then students would say 10, 5, 2.5 depending on the grade level.  If the prompt is doubling and the starter number was 50 the students would say 100,200,400 etc.

This can be a fun, energetic, academically rigorous game that gets students very flexible with math facts.  Look at your standards and pick your rules based on what the students need to know!

## More Great Math Routines

What is a math routine?

A math routine is a whole class math activity that you do overtime.  There are a variety of different types of routines.  You can do routines to:

1) Build Number Sense

2) Build Vocabulary

3) Build Conceptual Knowledge

4) Build Mathematical Modeling Skills

5) Build Procedural Fluency

6) Build Strategic Competence

7) Build a Strong Mathematical Disposition

When:  Anytime (they usually last between 5-10 minutes once the students know them)

How:  Routines are set up in a variety of ways – individual, partner, small group or whole class

Ideas:

1. Half It!  Teacher gives an even starter number.  Kids verbally toss it around the room- each child halving it until you get to the first odd number.  So for example,

Starter number 20 – Trevor says 10 – Mica says 5 – we stop.

Starter number 200 – Michael says 100 – John says 50…they keep going till they can’t go anymore

Starter number 1/2 – Carlos says 1/4 – Trina says 1/8 ….

2. Double It!   Teacher gives a starter number and kids verbally toss it around the room…this time doubling the number.

3.  Number Line It! –  Draw an unlabeled numberline and then have the students plot numbers.

Teacher says…draw a numberline…start it with 500 end it with 1000…write where 650 is…write where 899 is….

Teacher says…draw a numberline…start with 2/3 and end with two and a half…write where one and a half goes…write where 1 and 3/4 goes… write where 2 goes

## More Math Energizers

Here are some more elementary math energizers!  Have fun playing them and let me know how it goes.  I would try to integrate energizers into the schedule everyday as a quick way to review mathematical concepts.  The students look forward to these games and they learn a lot of math too!
