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.
Learning centers provide many opportunities for integrated learning. While playing in an imaginary grocery store, children learn math through the use of numbers and prices, literacy by recognize familiar labels on foods and develop social skills through role play as the shopper, cashier or manager and develop their physical skills by learning how to arrange cans and groceries in make-up shelves.
In addition to mental math activities, children should be given grade level mathematics workbooks to strengthen their math skills. Parents should have these books and other subject content books at home for additional practice and homework. These can be purchased from bookstores, teacher supply stores and multiple-purpose department stores where school or office supplies are sold.
Also, when the child is in the second or third grade and their child can't add simple two digit numbers, it is up to the parent to make sure that their child gets the extra help needed to become successful. Parents cannot wait on the school every time their child has an academic deficiency. Part of being a good parent is making sure that your child functions at the correct grade level throughout their academic career.
