The focus is on using length, such as a length of streamer, to compare two lengths that cannot be aligned. Such as the length and width of a table, this table in this room and that table, the height of a chair and the width of a table, a vertical and horizontal like, the circumference and height of a Pringle container, two different curved lines, distance around a shoe and the length of an arm.

The focus is that the non-standard unit must be the same for a given measure, with a special focus on precision. Using, for example, icy pole sticks, feet lengths, to compare length and width of a table, how many icy pole sticks is the same as two tables.

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.
