Halving Odd Numbers Partition Tens and Ones WORKSHEET DESCRIPTION
This worksheet provides practice of halfing two digit odd numbers.
The method used in this case is to partition numbers into tens and ones, halfing each part and then combining the answer. For example: half of 47 is half of 40 + half of 7. Half of 40 is 20 and half of 7 is 3.5 so half of 47 must be 23.5.
Firstly, learners will look at halfing each odd single digit number using counters as a visual aid. Students will then see an example showing how the model (which is similar in structure to a part part whole model) is used, before answering 11 questions.
