Leilani's Maths Problem Solving

It has been a few days now that we have been learning to add up numbers by tally marking.

This was today's Maths problem.

Here is how Leilani used her Tally Marking knowledge to solve the above problem. She showed two groups of 5 using tally marks and another group of 3 and counted them together: 5 + 5 + 3 = 13
Ka pai, Leilani. That was a quick way of counting two groups of 5 and then adding another 3.
