Longer or Shorter - PowerPoint

In a Year 1 mathematics teaching resource, the concept of measuring length is introduced through the comparison of objects using the terms 'longer' and 'shorter'. The lesson aims to help young learners grasp the meaning of length, which is defined as the distance from one end of an object to the other. Students are presented with visual examples, such as comparing the lengths of two whales, to identify which one is longer and which one is shorter. The blue whale is used as an example of being longer because it has more length than the grey whale, while the grey whale is described as shorter in comparison to the blue whale.

The teaching resource includes a variety of interactive activities to reinforce the understanding of length comparison. Students are encouraged to examine and compare the lengths of different objects, such as footprints, worms, fish, trains, pencils, and scarves, and answer questions based on these comparisons. Worksheets provided in the resource prompt students to circle or colour the longer or shorter object and even draw their own representations of a longer carrot or a shorter scarf. The activities are designed to be engaging and educational, helping children to confidently use the words 'longer' and 'shorter' in the context of measurement.
