what is term standard unit
Answers
Explanation:
Standard units are the units we usually use to measure the weight, length or capacity of objects. The standard (metric) units that would be discussed at primary school would include: grams and kilograms, centimetres, metres and kilometres, millilitres and litres (though children also learn about imperial units in Year 5 maths).
Non-standard units are used by children in Foundation Stage (nursery and Reception) and Year 1, to introduce very young children to the concept of measuring without them having to read any scales. Reading scales of any kind is a challenging skill in itself, so the idea of non-standard measures is to focus the child on the concept of heavier, lighter, longer, shorter, etc. before they go move onto the next step of measuring using standard units.
To measure weight, a child might be given a lever balance (like the one below), a lump of plasticine and lots of equal-sized blocks.
