Lesson 16

LEARNING & TEACHING SEQUENCE

WALT (We are learning to): Use a ruler and scales to measure objects. Understand that we measure in centimetres and grams. Compare objects we have measured and make a statement about them.

All learners in the class were working independently on the same activity after some whole class direction. Each group spent time at the teaching table during the lesson to check in on progress and scaffold/teach any areas which individual groups/learners were struggling with.

Teacher Notes/Planning

Revise: How to measure using a ruler. How to work out which object is longer. How to work out the exact difference between two objects of different lengths.

How can we do this using the ruler to confirm our answer?

What is the difference between how long an object is and how heavy an object is? What are some reasons we would need to weigh an object? Why would be have to be precise? What unit of measurement do we use when we are weighing something? Introduce grams. Show on the scales how to make sure they start at zero and how to read the grams. Have learners select objects around the classroom to weight and compare.

Reflection

Learners recalled working on measurement and measuring in centimetres earlier in the year. They remembered the importance of starting to measure from zero to get a true reading. Learners really enjoyed having some choice as to what they could measure/weigh and for the most part made sensible decisions. Unfortunately a part of the lesson recording was interrupted due to the leaf blower outside our window so this is missing from the video. It was great to see the whole class engaged with this activity and they were very keen to continue into a second day. This engagement allowed me to focus on learners who needed additional support and scaffolding - some learners definitely struggled identifying “how much” longer an object was when compared to another object. Several learners did struggle with which side of the ruler to use (despite me teaching this as part of the whole class lesson) and measured in millimetres rather than centimetres - we addressed this as a whole class in a subsequent lesson.
