Crossing the 10.

 

With today's lesson, we will be using a number line to help us to cross the ten when adding.

 

 

45 + 8 =

 

so we split this up in to two small sums. For the first one we use our number bond knowledge to get to the next multiple of ten.

 

45 + 5 = 50

 

 now we are at 50 we need to add the 3 to get to our answer which is 53.
