Base 10 concepts begin in Kindergarten. At this early age, base 10 refers to the ability to understand that in a number like 12, the one represents 1 ten or 10 ones, it no longer is the same as 1 when 1 is in isolation. It is also showing the ability to count onward when 10 is recognized, looking at a group of 10 and automatically knowing to count up to determine how many there are when there is a group of 10 and 5 more or 6 more.
Although this concept sounds simple, it's quite difficult for new learners. This article focuses on teaching strategies for the kindergarten learner, using the Common Core Standards for understanding and decomposing numbers from m11 to 19.

When you think of algebraic reasoning, I'm sure that kindergarten is the last thing on your mind. However, algebraic reasoning occurs as early as kindergarten and is certainly one of the benchmarks in the Common Core Standards. This week, I've written an article about how to address subtraction to five, addition to 10 and what it means to reason algebraically in kindergarten. The strategies in this article address K.0A in the Common Core Standards.
Khan's Academy just went live with a variety of online math activities to address the Common Core State Standards for grades Kindergarten through to grade 12. For those new to Khan's site, he provides a wealth of tutorials on math for practically every concept from kindergarten through to college. The Common Core activities are free and offer a differentiated approach but don't take my word for it, check it out.

What should children know in math in Kindergarten, 3rd grade, 7th grades or any grade for that matter? Many states follow the Common Core Standards which relate closely to the NCTM standards and of course there are sets of curriculum or standards that vary somewhat, depending on the educational jurisdiction. For a quick glimpse at what is expected from a pre-school level through to grade 12, you'll find the grade by grade goals to be quite helpful. When looking through the standards, curriculum or grade by grade goals, remember that these expectations are meant to be achieved by the end of that year.
