Double digit addition

The last two weeks we have been getting into double digit addition! We started adding using just our tens. Some examples 10+20=30, 70+30=100. Now we have gotten into adding using our tens and ones with no regrouping. The students love using the plates and their manipulative to add. Some examples 12+54=66, 73+25=98. After spring break we will be introducing other strategies to add two digit numbers such as make 10 to add, use a 100 chart, ten more the less.
