Mathy Monday-Crossing the Decade *freebie*

Today's math game is about crossing the decuple in math.  If you don't know this means going from one decade of numbers to the next, for example 28, 29, 30.  My math group has great difficulty crossing the decade when counting back.  This is important, because the students will need this skill when learning to do subtraction and counting back to answer subtraction problems.  Also, some of my math kids have difficulty recognizing and naming the numerals 13 and 30 or 15 and 50.  This activity shows them where 15 and 50 (for example) are in a series of counting numbers.  

Materials you will need:

Board game, dice or arrow cards (if you use dice-write the numbers 40, 50, 60, 70, 80, and 90, if you use arrow cards use 40, 50, 60, 70, 80, 90) , markers or pawns to move on the game board

Find a copy of the game board HERE

Directions:

Student 1 rolls the dice or draws out an arrow card. Student will move pawn to the space on the game board that is the number before the decade number they rolled or pulled out.

For example:  Student rolls 60, student will move pawn to the 59 on the game board.

Student 2 takes a turn, following the same directions.

The first person to the finish wins.  This game goes quickly, but I have my student play several times with a different partner each time.

Modifications: Have a numeral roll available so the student can look back to find the number and see what is before.  Have the student start at a higher number and count back, to get the rhythm and pattern in mind before moving his or her pawn.

I'm also linking up for Made It Monday!! :)  Hope you enjoy this game!
