Recognise numbers to 20 and then beyond. Write out each number 0-20 on separate pieces of paper or use printed number cards. Can you read all the numbers. Can you find a number someone says. Can you put them in order. If confident, add the next set of ten. 20-30 and so on. Play splat with the numbers, fire water pistols at numbers in chalk, place numbers on floor and try to hit the correct number with a ball/beanbag.
