He is 7 and homeschooling via zoom. Teacher did some work where the kids had to use a model bar to multiply lengths of metres cm and mm, to make the larger length. as in - the house has storeys 4m 30cm and has 5 storeys. how tall is the house? As if multiplying and division in lengths isn't hard enough!
Instead of a straightforward multiplication in columns she did 4x5=20. 3x5-15. add them together and then some other shit. I just didnt understand it. Then a similar thing with division. Just gave the lengths of rope and said x 5 will give us the length of the uncut rope. Another example ...we have 350, halve it to get the two lengths of ribbon. But no explanation of how to halve that number. I think DS is very average so he couldn't even get started.
AIBU to say just teach in a secondary level way, but keep the numbers very simple. I am not talking long division here, or fractions of numbers (we also had those along with the metric shit) Yesterday was horrendous
