I had the pleasure of meeting Ms Wykes about 5 or 6 years ago. She is one of the prep maths teachers at Roedean girls here in Johannesburg. Ms Wykes has given me permission to share this maths worksheet with you:
Using the calculator to convert percentage, Decimals and common fractions
The worksheet is appropriate for grade 7 maths students.
If you have worksheets of your own that you would like to share with your fellow teachers, you can send them to me via tal@smdtechnologies.com and I will create your own page. You can share the link with your students and choose whether or not you want to share the memo.
