mnożenie jako skalowanie z ułamkami zwykłymi Explanation: Here, scaling refers to 1/2 more of something, 1/3 less than something, etc. ccccccccccc The children could work in a small group to make 2D drawings of objects in the classroom. They measure heights and widths of their objects and then scale them down. They decide their own ratio for scaling down, for example, 1:2 (half the size) or 1:3 (one third of the size). Make the point that scaling down is the same as multiplying by a value less than 1. https://garyhall.org.uk/maths-objectives/166/solve-problems-... cccccc Mnożenie jako skalowanie, z ułamkami zwykłymi (film) | Khan Academy https://pl.khanacademy.org/math/arithmetic/fraction-arithmet... |
