The Why & How of Number Sense

 “If you are a parent of a child in the K-12 system, there is today just one thing you should ensure your offspring has mastered in the math class by the time they graduate: number sense.”  Dr. Keith Devlin, mathematician at Stanford University   Number sense is the single best indicator of students’ success in math.  It is critical in the Common Core State Standards in math, and is the reason curriculum companies have built

9 Activities for Building Place Value and Number sense in the middle grades with base ten blocks

Building Place Value and Number Sense Skills

When I was an interventionist looking at our schoolwide data, I noticed something in our students’ math data.  The students in third grade that scored lowest in math overall on our benchmark testing (NWEA’s MAP test), were the lowest scoring in the place value and number sense sub-domain. As time has gone on, I’ve continued to see that trend- that the lowest achieving students in math, tend to have poor number sense. Here are some

Number Sense Activities and Resources

Number sense is the single best indicator of students’ success in math. As adults who are successful with mathematics, we have memorized steps and methods that work best for us. We have facts memorized.  We use our number sense to do mental math quite frequently.  We struggle to see the point with the crazy and convoluted steps students are asked to do because we no longer have to think through problems the way students do.
