LI: To learn adding in parts and place value adding. .
Mr Wong's maths groups had made a chart for adding in parts and place value addition. Mr Wong had linked us into a PDF which had four different problems in it. We had to work out these problems using these strategies. 
What is Place Value Addition? - Place value addition is when you have big or small amount numbers for example 3285 + 3728. You first add the ones up to the biggest place value unit in the number. The biggest place value unit is thousands. 
What is adding in parts? - Adding in parts is also  when you have numbers. You need to try find teh answer by making tidy/super tidy numbers. ( A tidy/super tidy number is numbers ending with 0. A super tidy number is a number that has more than 2-3 0's.). You need to add the numbers that you think is the most tidiest numbers.
