Addition facts within 10 - 1st grade math

Check out my videos on this page at my site! They present an organized and logical method for children to learn their addition facts within 10 using PATTERNS that arise from the number system itself.

Children LOVE patterns, and patterns are the essence of math — mathematics has even been defined as the "science of patterns".

In this method, we study sums with 5, sums with 6, sums with 7, and so on until sums with 10 (also called "number bonds"). These sums or number bonds are not studied in random order, but grouped by the SUM, or the "answer".

New book in the Blue Series: Data and Graphs

A new kid on the block!

Math Mammoth Data and Graphs is a worktext that covers common statistical graphs and some related topics for grades 2-5.

It is a worktext, which means it includes both the "text" (instruction) and the "work" (exercises and problems).

The book starts with the easiest topics: reading and making bar graphs, pictograms, histograms, and various kinds of line graphs.  Toward the end of the book, we also study average (also called the mean) and mode, and how these two concepts relate to line and bar graphs.
