Discuss these topics with your children when you are studying the number one.
The sun and the moon.
What the children looked and acted like when they were one. You many want to have them bring in any pictures or clothing they have of that time.
Single animals that are hatched from eggs.
You can also add measuring cup & spoons to your water or sand box. Children can count how many scoops it takes to fill a cup.”

When we learned about dinosaurs we had a fun activity for the kids. Fill a water table and give the kids “islands” to float. We cut foam meat trays into different shapes for the islands. We then gave the kids plastic dinosaurs of all shapes and sizes. They then had to place the dinosaurs on the islands until they sank the island. Our kids had so much fun with this they still ask us to play and we did that theme 2 months ago!

Cut out foam pieces into ‘bones’, hide these pieces in your sensory tub, after your child digs them all out, use paper clips or a stapler and see what you and your child can arrange them into. Or let them glue them onto a piece of construction paper.

Tape maps to the tub and have the children drive their vehicles over paint soaked sponges and make tire tracks all over the maps.

For our sensory table, we just finished a Winter theme. I froze small toys in ice cube trays, and in various size containers and placed them in the sensory table. The children were given plastic and wood mallets and told to chip away the ice to find out what was inside! They had a wonderful time, and the amateur “archeologists” would rush to me to show me their “prize”! I’ve already been asked when we’ll do it again

To show children about insulation and bears thick coats you can spoon a large amount of Crisco into a plastic bag have your child put a plastic bag on their hand and their hand in the Crisco, squish it around to get it entirely covered.
Put their other hand in two plastic bags. Now have them put their hands in a bowl of ice or snow. Which hand can stay in the bowl longest? Talk about how a thick hide of fat & blubber keeps the bear warm in the winter …

This one is easy, pour warm or semi hot water into your tub, float a bowl of ice cubes in the middle, talk about hot/cold, what happens if you put the ice cubes in the warm water?
You can do soft/hard with feathers or cotton balls and rocks or blocks. Light and heavy with the same objects. Clean and Dirty. Inside – Outside. Smooth – Rough. Wet – Dry. Use your imagination there are tons of possibilities.
