Most kids are good at counting forward, but counting backward is a different ball game. Practice counting down by filling in the blanks with the right numbers.
Does a sea star live in the air? Or underwater? Ask your preschooler to sort out the object into their correct categories--"up in the air" or "underwater."
Challenge your kid to fill in the missing numbers from 1 to 50. This is an essential skill for understanding numbers beyond just counting them from memory.
