Hello. The best way to teach kids math skills is through their primary learning tool – play! This means that in these early years, children don't need formal lessons, worksheets and workbooks, or anything that looks more like "real work." If you want to introduce your child to math, then the best thing to do is with math is fun , you can immediately think about numbers and try to teach a preschooler to count, recognize numbers and add or subtract them, but in fact these are some of the most advanced math skills in early age.
