Key Info
  • Finding numbers on the number line
  • Duration: 03:22
  • An explanation of how to read numbers on a number line and how to speed up the process to be most efficient, demonstrated by the animated characters Star, Sky and Hutch. The first number line is read to find tens. Next, 58 is found on a number line using first the tens and then the units to find the number. A group of children form a human number line and expand the range of strategies which can be used for reading numbers on a number line. To find 78 it is faster to find 80 and then count back 2. Similarly, 63 is nearer to 60 than 70, so it is faster to find 60 in the tens first and then count on the units along the number line. Numbers ending in 5 are always half way between the 10s. To find numbers in the hundreds you can use exactly the same method as for smaller numbers.
