Sovlving Strategies

This week our group of five did solving Strategies. We did them one by one as a group.

We did written algorithm, addition, subtraction, place value a number line etc.

The different kinds of strategies are -
Splitting Numbers
Number Line

This is an example on how to do the split subtraction. 7= 4 & 3 84- 4 = 80 80-3 = 77
                                                   

Example for counting forward 77, 78, 79, 80, 81, 82, 83, 84.

Example for place value. 476-300= 176 176-50= 126 126-3= 123 300+50+3 = 353.

The example for subtraction. 23-22=1 0.63.-0.12= 0.51 1-0.51= 0.49.

This is the Addition example. 5+5+5+5+5=25

Example for Skip counting. 5,10,15,20,25,30
