Draw a number line GAME

outside number line

Go outside and use chalk to draw a number line to 20 (you can also use a big roll of paper and do it at home). Use 2 dice, one with numbers and second with + and -. Roll a die to see from which number you should start, then roll a second die to see if you need to go one more or one less. The person that gets to number 20 first, wins.
