How do I introduce my kid to addition and subtraction? Is there any internet tool for me to support?

This is much the way it is done at school.AC130Nav said:I would start with blocks, maybe. Then pennies and dimes (reflecting our decimal system).
I wrote a flash card like program for a young neighbor that seemed to work but it really needed verbal along with the visual. That's what you should be looking for.

Counting starts with numbers of objects. The it is a matter of grouping objects into smaller numbers.

I don't think the Cuisenaire rods were around when I was in 1st grade back in the early 50s, but when I first heard of them, they seemed like great devices to teach all four arithmetic operations, making somewhat abstract operations much more concrete.vanesch said:Remember using those in first grade ! However, I think they come AFTER the conceptual understanding of what addition is: namely "how many" we have when we "put the heaps together and count again".
Those rods are great tools because the bars already represent "heaps".
They are even better tools to introduce the subtraction "what rod is missing ?"
In fact, there are several conceptual ways to look upon addition and although for us they are of course "equivalent", for youngsters, they represent different conceptual ideas. The concept that D H introduces (I guess coming from the logical definition of the natural numbers :-) ) is a different concept for a kid than what I mention. It should also be introduced (but I'm not sure it should be introduced *first* - we could discuss about that). D H talks about addition as repeated "is the successor of". I talk about "counting the two heaps, and then counting them as one heap". The rods could be seen as pre-defined heaps, OR as abstract numbers and a puzzle which defines an abstract addition independent of "counting" (a bit like "if you mix yellow paint and blue paint, you get green paint" - if you put together the violet rod (4) and the green rod (3) you get the "same as" the black rod (7).
violet + green = black.
4 + 3 = 7
One way to make learning addition and subtraction fun is to use visual aids such as counting objects or using pictures to represent numbers. Another idea is to incorporate games or activities that involve adding and subtracting, such as a scavenger hunt or a board game.
Most children are ready to start learning basic addition and subtraction concepts around the age of 5 or 6. However, every child is different and it is important to consider your child's individual development and readiness before introducing these concepts.
One helpful strategy is to use real-life examples and situations to demonstrate addition and subtraction. For example, you can involve your child in tasks such as counting money or sharing snacks equally between siblings. This will help them see the practical applications of these math skills.
Some common mistakes children make when learning addition and subtraction include forgetting to carry over when adding larger numbers, mixing up addition and subtraction symbols, and not understanding the concept of regrouping when subtracting. It is important to address these mistakes early on and provide plenty of practice and reinforcement.
Consistency and practice are key to reinforcing addition and subtraction skills. You can continue to support your child's learning by incorporating these concepts into everyday activities, providing worksheets or online games for practice, and celebrating their progress and success.
