Interpreting One-colour Trains as Fractional Parts

In this resource children are asked to build all of the possible one-colour trains to match the purple rod. Fitting them underneath they then resemble a fraction wall where children can describe the fractional parts of the whole purple rod. They then investigate the other coloured rods and their fractional parts, for example halves and quarters and thirds and sixths. This activity is a way of introducing or reinforcing fractions as part of a whole and fraction families using a concrete, visual representation. It could be used as a whole class activity or with small groups of children. Cuisenaire® Rods are a useful mathematical resource which provides a concrete representation as a bridge to developing more abstract mathematical thinking. This activity, provided by ETA hand2mind, is an example of how Cuisenaire® Rods may be used to teach and practise mathematics.
