With little ones:
Have students use all kind of things in the house to measure - non-standard measurement
Explore comparing non-standard measurements

With older children:
read recipes; bake; measure their rooms; estimate elapsed time of a walk around the block
Challenge:
baking - give them a 1/4 cup or a tsp to bake a recipe. See how they need to use repeated addition or multiply to complete the recipe
math or spelling drill - measure how much time it takes to complete a drill sheet and keep a graph of how much faster it's completed each time
Service learning:
We are cleaning-up a section of the cat-walk behind us and then estimating how much time it would take to complete and/or how many people to complete in an hour. We are also going to measure the stairwell and estimate the amount of paint it would take to repaint it. When not on stay at home orders, I'm hoping to have daughter write message and I'll post on Nextdoor for white paint donations, and then see how close we are to how many gallons we estimated for the project. She can document the project in a process journal and then share with other families in our neighborhood and hopefully do the same once we can all head outside. Maybe we'll do a community hike around the different stairwells in our neighborhood and celebrate when we can or do a Zoom celebration all together if we are inside for the long haul.
