Measuring With Non-Standard Units

Last week we learned to measure length with non-standard units. In one of our lessons, the students worked together to make predictions about the length of a craft sticks using non-standard units of paper clips, color tiles, and lima beans. As they made their predictions, we discussed which unit we would need to the most of when measuring the craft stick. We talked about that when measuring with a unit that is smaller, you need more of that unit and when measuring with a unit that is larger, you need less of that unit. After making their predictions about the length of the craft stick and recording them on construction paper, they measured the actual length. We talked about starting at the end of the craft stick because just like in a race, everyone needs to start in the same spot to be accurate and fair. After recording their actual measurements, the students compared their predictions to the results.
