Today in Math we are learning to solve addition and subtraction using reversibility and place value.
Mele and I had to use screencastify and video our work.
Place Value: In Maths place value is used to separate numbers and figure out the answer.
Reversibility: When you are using reversibility, you have to reverse the multiplication equation and make it into a division problem
Watch my video below to find out how to do reversibility and place value!
