Some have a time limit to complete tasks, much like a game. If the math problems are not completed in time, a buzzer sounds indicating that they are out of time. This raises the competitive level from simply completing tasks to competing for how quickly they can do it, and do it correctly.
Elementary teachers and parents play the biggest role in a child's mathematical development, especially from Kindergarten through Fourth Grade. Time spent in school learning math or not learning math can never be replaced. Parents should make sure the elementary math teacher is knowledgeable and is a good teacher.
Go on a counting scavenger hunt! For young children, you can keep the hunt simple and indoors, go on a hunt and count how many bedrooms, windows, doors, bathrooms, etc are in your house. For older children, you can even take this adventure outside. Look for certain kinds of animals, plants, flowers, you name it! Add in another element of fun (for any age) and create a graph for them to track their finds!
Children naturally love counting and doing puzzles, but for some reason, when you call it "math", all of the interest flies out the window! So how can you cater to this natural love of 'math' and keep it fun and interesting enough to keep children's interest?!
