My son seems to forget work that we have done, or a question I ask him and repeat the next day he has forgotten.
Any tips or anybody with similar experiences?
Its just the case of going over the material again and again.
With regards to maths, for example if you have worked on how to decimals for a week, similarly fractions for a week and then percentages for week (i.e. main topic per week), chances are if you come back to topic 1 after three weeks, child would have forgot on how to deal with decimals or fractions, if that is the case, I believe there should be 10-20 short question on these main topics every day and they shouldn't take longer than 20 mins to complete.
Hope its useful but feel free to update if this doesn't work.
Happy to help.
