We were adding with our Tens and Units boards. We added numbers like this
Tens Units
2 7
+ 1 5
We got strange numbers like 3 Tens and 12 Units. You cannot see that on the 100 square. We learned how to fix it.
We swapped 10 Units for 1 Ten. That’s a fair swap. We made a new Ten to add to the other Tens. Our answer was 4 Tens and 2 Units. That number is 42. 42 is on the 100 square. Well done.
We worked on Mrs Quinn’s interactive whiteboard as well.
