Sugar Cube Tower Math for Preschoolers

Today the blocks are taking a break and we’re building a sugar cube tower. Kids will be dazzled to build with sugar, and their jaws will absolutely hit the ground once they start adding colors to them, too.

Sugar cube tower math is “sweet!”

When you think of math for preschoolers + building, you probably picture blocks.

Maybe you picture wooden blocks.

Perhaps you envision foam blocks.

But, sugar blocks?!

Oooh, friends, there’s a new kid in town for building that your kids are going to LOVE.

Kids (and adults!) can get bored practicing the same skill, the same way, with the same things, day after day. We can stimulate kids’ curiosity by providing unique opportunities to practice the skills.

It’s like cutting skills: cutting on paper is important for practicing scissor skills, but if you only cut on paper, it can get boring.

When kids get to build with sugar cubes, their excitement and learning will be through the roof.

There’s more math fun where this came from:

Sugar cubes – they’re about $3 per 1 lb box in the grocery store
Water
Clear cups
Eye droppers or spoons – we use eyedroppers all. of. the. time. and they’re one of our favorite classroom supplies
Coloring – ex: liquid watercolors, food coloring, diluted paint
Large, shallow tray – regular and giant baking sheets are perfect for this

Directions

Open the boxes of sugar cubes and set them out with the entire top of the box torn off.
Fill clear cups with water and add a splash of coloring. To each cup of colored water, add an eye dropper or spoon.
Put out the large, shallow trays.
Build sugar cube towers!
During the building process or when the tower is complete, invite the kids to add on the coloring. As the coloring absorbs into the sugar cubes, they will slowly begin to dissolve and it’s hilarious chaos.

How do you make a sugar cube dissolve faster?

Observing the process of the sugar cube dissolving process is half of this activity’s fun.

First, it’s a solid cube, but then it dissolves and falls a little, only to end up in a flat puddle of wet sugar. Kids race to build their towers before they dissolve completely and it’s so fun to watch.

But, you also add more science to this by exploring how to make the cube melt even faster.

To conduct this experiment, provide the kids with cups of cold water and warm water and invite them to test out which makes the cube dissolve quicker.

A child uses two hands to get color to add to the sugar cubes and moves some cubes around. The cubes are beginning to dissolve and the tray is mixed with colors.

Are preschool math activities part of STEAM?

Yes!

STEAM is a juicy acronym used frequently in education and each letter represents a different part:

S – Science
T – Technology
E – Engineering
A – Art
M – Math

STEAM learning is when kids apply some (or all) of the above letters. Kids naturally explore STEAM learning without any adult intervention, but it’s still fun to set up extra STEAM activities for them to explore.
