Robot Rules Function Tables I love function tables for practicing facts! Not only do students develop fact fluency through practice, but with function tables they also develop a deeper understanding of the relationship between the operations. I've just finished up my first Robot Rules product--a Valentine-themed set for addition and subtraction--and I wanted to give you a closer look.One option for the cards is to laminate them and place them in a workstation with wipe-off markers. I would definitely suggest, however, using one of the recording sheet options to provide accountability and serve as a formative assessment.

Number Rack by The Math Learning Center Overview Number Rack facilitates the natural development of children's number sense. The movable, colored beads encourage learners to think in groups of fives and tens, helping them to explore and discover a variety of addition and subtraction strategies. About Us Pat'sBlog: Why M for Slope Over the many years I taught I developed a keen interest in the origin and use of the symbols and terminology of math. When the internet came around I jumped in pretty early with a web page on Mathwords, contributing on the Dr Math and Teacher to Teacher support Math Forum, and for several years, this blog. Over that time there are few questions that come up more often than the reason for the letter m as the symbol for slope in the standard American (and it does seem to be mostly American) linear slope intercept equation form, y = mx + b. Almost no one seems to ask about the b, which is even more curious to me. Interestingly, m for slope has led to more mis-history speculation in classrooms than any other topic, with the possible exception of the life of that Great American-Indian Mathematician, Chief Soh Cah Toa.

Contexts for Learning Mathematics - DreamBox Learning I’m Cathy Fosnot, I was a professor for many years at City College of New York, I founded the Mathematics in the City, a National Centre of in-service for Math education and the author of various books and articles on mathematics education including the Contexts for Learning Series from Heinemann, and I am the Senior Content Advisor with the academic team in DreamBox learning. When children are constructing multiplication they often start by needing to build a whole system of ones. So, if the context is “What’s 3 x 6?”, kids will count out 6, count out another 6, count out another 6, make sure they have 3 groups and to get the answer they go all the way back and count from 1 again. Eventually they begin to skip count and use repeated addition, and repeated addition usually builds into kids beginning to realize they can regroup groups.

Engaging Hundreds Chart Activities **This will be a 2 part post in which I will discuss different ways to engage students in activities using hundreds charts. Each post will include three activities to engage students.** The hundreds chart is a tool for students to explore and think about the number system. Number Frames Overview Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range. The frames help students see quantities as equal groups of other quantities and in relation to benchmark quantities. This helps primary students move away from one-by-one counting toward more efficient ways of counting and computing. As students advance, custom frames can be constructed to help visualize factors, products, fractional parts and more.

Using Number Bracelets to Develop Number Sense I've blogged recently about using dot cards and rekenreks to develop number sense, and today's post focuses on another great tool--number bracelets. Like dot cards and rekenreks, number bracelets provide concrete practice for number combinations and composing/decomposing numbers. Making Number Bracelets
