They can start with asking simple math questions and going on to harder questions, as the child gets older. Parents should continually ask children mathematical computation questions and give positive feedback when they respond. Children love to receive positive feedback and that encourages continues growth.
Sort it out! The sky is the limit when it comes to finding things to sort! Candy, beans, cotton balls, paper clips... you name it! You can even change around how you want it sorted... one time, sort by color, the next time sort by size or shape! My son had a BLAST when I pulled his Matchbox cars to the school table and we sorted them by color! For younger children, you can make it easier by having 'color cards' and have them match the specific objects to the correct card. Older children can just be told to sort out the items by color, shape, etc.
Parents who are positively involved with their children and want the best for them will make sure their children are keeping up with their math skills and are successful in school.
When trying to develop good math students, all avenues should be tried. Parents can make additional progress by allowing children to visit work locations that utilize a lot of math. Children should be exposed to as many careers as possible. Careers in math and even science should be on their list of considerations. Parents should inform children which careers require them to have good math skills.
