One to One Correspondence

This concept is so fundamental that we often don't even think about it. Most people want to jump right into teaching children to count 1-10. While Rote learning (memorizing counting numbers) is a handy tool, it can just be like singing a song and have no meaning to them. In order to lay a strong foundation for mathematic understanding they need to fully understand the meaning behind each of those little numbers!
One-to-one correspondence is the ability to match numbers to objects or object to object; for example, the numbers one to five matching five blocks, or matching one sock to one shoe.
Children (all people really) learn best by using concrete examples, hands-on and FUN learning! 
That's why at St. Jude's we spend time planning and making sure students have lots of opportunities on a daily basis to put their hands on learning!
