The Common Core Place Value standards are so important when teaching first and second graders. Understanding the meaning of ones, tens, and hundreds sets the foundation for counting, adding, and subtracting. When I teach place value, I emphasize the use of manipulatives with my students. I especially have success using place value blocks. I like place value blocks because students can see that a ten is composed of ten ones and a hundred is composed of one hundred ones.Place value blocks are also easy to manipulate.
