Curriculum for Pre-kindergarten

Students learn the meaning of same, different, alike, larger, and smaller. They identify and match objects based on size, color, shape, and even purpose.

Identify two out of three objects that are the same

Build an understanding of the word "same." The identify which two objects are the same when shown three objects

Identify two out of three objects that are different

Practice the difference between "same" and "different." Then look at three objects and choose two objects that are different

Identify whether two objects are the same or different

Practice comparing objects. Look at two objects and tell whether they are the same or different

Identify which of two similar objects is larger

Practice comparing objects. Look at two objects that look alike but are different sizes. Tell which one is larger

Identify which of two similar objects is smaller

Practice comparing objects. Look at two objects that look alike but are different sizes. Tell which one is smaller

Match pairs of similar items that differ in size and/or color

Match pictures that show the same object. The objects may be different sizes or different colors, but are alike because they show the same object

Match pairs of similar items that differ in size and color

Match pairs of similar objects that differ in size and color. Look at pictures and match the pictures that show the same object, even if the color or size is different

Match pairs of different items that are used together

Match pairs of different objects to show which ones are used together. Instead of matching the same objects, this time you match objects based on what objects go together or what objects are used together

Students build upon their understanding of size, color, shape, and purpose to sort dissimilar objects based on a common attribute. They must also ignore objects that do not fit the given descriptors.

Identify objects that belong to a given category

Practice sorting objects by type of object. Feed a creature objects in a given category by clicking on all of the objects in that category
