Point to the object as you recite each number name. Use fingers to count. Help your children count without skipping numbers or counting something twice. Sort objects looking for differences, like which box is bigger. Talk to your children about what numbers are used for, such as keeping score in a game, or finding an apartment or street address.
Young children can learn about angles, shapes, and solids by looking at the physical world.
Spatial sense gives children an awareness of themselves in relation to the people and objects around them. Ask them to identify and describe different shapes, to draw them in the air with their finger, to trace over them with their fingers, and to draw them on paper. Children learn geometry best through hands-on experiences. Things they can touch and manipulate are particularly helpful, like blocks, boxes or containers, shape sorters, and puzzles. Even cutting the sandwiches they eat into different shapes and letting them fit them together or rearrange them helps children learn about geometry.
