3m 55s
Even though at this stage many students are ready for rulers and cm this is still worth doing. Tasks such as make and draw some rectangles (triangles, trapeziums) using 12 icy pole sticks, draw a line 5 sticks long then check it.

The focus is first on metres (metre rulers) and centimetres (30 cm rulers). Later can introduce mm. Draw a line 10 cm long without using a ruler then check (emphasis on precision) draw a line 1 m long on a page, estimate and measure the length of a table, draw a rectangle 20 cm around than check.

Sometimes we use a scale that does not start at zero (weighing a dog). The idea is to compare, order and measure objects using a broken ruler or a measuring tape.

The focus is on experiences that have students using realistic estimates of the lengths of objects such as the width of a room, how far they can jump, the width of a page, estimate then measure half of this line.
