Number Sense, Grades 3 Through 4 Simple Effective Number Sense Experiences

As a math teacher, I love to refer to this book and use theactivities often. I especially liked the section on decimals.Students can have difficulty realizing how big or small a decimal is and there is an activity that allows them to group the pictoral and the number version according to its size. It allows the students to see that a decimal close to 0 has very little shaded pictorally and that the decimal number starts with 0, 1, or 2. That is very important for those visual learners. Also, the estimation activities are very good because it covers estimation in terms of how many are in a space and estimates where rounding and then performing an operation are necessary. As a math resource teacher I have people coming to me a lot and when I show them activities from this book they are pleased and one has even bought it herself!
