Children will explore their senses with an engaging and simple Earth Day math sensory bin. It’s a great way to incorporate sensory play into your list of number activities for preschoolers.
Earth Day is a great time to talk with children about a variety of topics. For preschoolers, I tend to focus on using materials again in new ways, taking care of our homes and neighborhoods, and other concrete concepts they’re able to grasp.
This math matching activity is very Earth Day-friendly. We reused blue rice and leftover plastic eggs from Easter! So, not only will the kids be learning important math concepts and all about Earth Day, but they will also be actively using something that is crucial to protecting our environment – reusing items as much as we can!
Are you following Fun-A-Day’s SPACE THEME Pinterest board?
It’s also a great time to plan for a space theme, especially if the kiddos are enamored with outer space and the planets. This simple Earth math sensory bin would work well around Earth Day, during a planned space theme, or just because.

Prepping the Earth Day math sensory bin
I already had blue rice from previous sensory play, like this weather bin. I didn’t have green, though, and I wanted the base of the sensory bin to be Earth colors. So I put some rice in a bag, added a few squirts of green liquid watercolor, shook it all up, and voila . . . green rice! I set it in a pan to dry for a little while before using it.
While the green rice was drying, I grabbed some leftover plastic Easter eggs. I tend to have a stash of these both at school and in my craft closet at home. Using a black permanent marker, I wrote the numbers 1 through 10 on individual eggs, both on the top half and the bottom half.
I used the same marker to write numbers 1 through 20 on some condiment cups that I have. I love how this Earth-themed bin includes some recyables!

Setting Everything Up
I placed the blue and green rice as a base in a sensory basket. I have to admit that I attempted to make it look like water and land at first. But then I knocked into the basket and messed it up! 🙂 No biggie!
Next, the Easter eggs were added to the basket. I broke the pieces apart and placed them randomly in the bins.
I added marbles to the bin. In my mind, the marbles were indicative of little Earths since they’re spherical and blue/green!
The condiment cups were placed to the side of the bin.
How to Use the Earth Day Math Sensory Bin
Once everything’s set up, invite the kiddos over to explore the sensory bin and delve into some preschool math!
The children can use the eggs and condiment cups for scooping and pouring, along with their hands. The cups are great for filling and stacking, too!
The numbers on the eggs can be matched up and assembled. Take that a step further and have the children add the correct number of marbles inside each assembled egg. Illustrate addition by placing marbles into each side of the egg and combining them. Once all of the eggs are assembled, the kiddos can order them from 1 to 10.
Use the condiment cups to extend the counting and one-to-one correspondence up to 20 (or beyond)! Remove the odd number cups and just focus on the even numbers. Then have the children work on skip-counting by 2s up to 20.
What are the Kids Learning with this Math Sensory Bin?

Thanks so much, Lee! I keep a stash of items that I can reuse (both in the classroom and at home). It’s a mix of random items, but they sure do come in handy a lot!
The rice is SO pretty! I love that the simple addition of writing numbers on the recycled containers added so much learning!
I know I’m biased, but I think the rice is pretty too! 😉 Thanks, Devany!!!
You always make such pretty sensory bins! I love all the learning you can do with this one too!
You are too sweet, Danielle, thank you! 🙂
What a beautiful sensory bin! I love the number matching activity. I know our kids would want to fill the eggs with the rice as they were matching them up. They would automatically add music to the activity by making them into number shakers.
I’m actually surprised that we didn’t get some egg shakers made this time around! Thanks, Theresa!
This is fantastic use of reusable – I love the matching egg numbers.
Thanks, Cerys! I like reusing items like the plastic eggs – the kiddos always seem to find it amusing the different things we we can use them for.
I love your “earth”!!!! So cute! I wonder how long my kids would leave it like that?!?!?!
Thanks, Kim! I bet it would stay like that for about 2.7 seconds! I ended up messing it up even before the kids could get their hands into it!
I love the idea of using blue and green rice. So many great learning opportunities with this bin.
Thanks, Jodie! We’ve already used the rice for a few other sensory bins during Spring Break. 🙂
oh how we LOVE rice play! this is a great idea.
Thanks so much, Nicolette! 🙂
