My students LOVED learning about estimating and measuring.
The hands on activities really got them into the process and helped them better understand the concepts.
Here are the standards we worked on:
Measurement & Data:
Measure lengths indirectly and by iterating length units.
Order three objects by length; compare the lengths of two objects indirectly by using a third object.
Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.
We chose objects from our class to measure using Unifix cubes as our non-standard unit of measurement. The objects we chose were scissors, a glue stick, the classroom iPad, a pencil, a book and their pencil boxes.
We first estimated how many Unifix cubes we thought each object would be and wrote our answer in marker so no one could erase their answer when they found out the exact number!
Then we got to work measuring. We measured the book and iPad as a class then they got to measure the other objects on their own.
Many of the students thought their original estimates were funny because some were pretty far off. However, it worked as a perfect teaching and learning moment as I explained that estimating doesn't mean we will always be right and that the more practice we get estimating, the better we get.
Here are some pictures of them measuring:
