TOS Crew Review: Critical Thinking Press - Mathematical Reasoning B

Mathematical Reasoning B is from a new line of books from Critical Thinking Press which can be used a part of a core curriculum (primary curriculum source) or as a supplement. There is not a separate teacher book or answer key for this book. The introduction to the book supplies the necessary teacher information to compete the book.

The items covered are spiral, meaning that it teaches a topic and it comes up around again shortly. Each page covers a different topic. There are 264 pages in the book, so you would want to cover at least 1 1/2 to 2 pages a day for a one year curriculum. The lessons on each page are short so that doing so would not overwhelm a young student.

Students are expected to understand semi-concrete ideas. Meaning that they do have a basic concept of the addition concepts without the need of tangible objects. They state, however, if they do need it, you should supply the necessary hands on materials.

The beginning addition lessons start with adding objects in boxes, followed by adding using a number line, then basic addition is covered without any helps. Counting is reviewed by filling in missing numbers on a page. Geometry, counting money, number words, number patterns, following the directions, fractions, subtraction, measurement, data processing and probability (long for bar graphs,) and word problems are all covered at the first grade level. Also, because this is from Critical Thinking Press, you can expect to find critical thinking problems sprinkles throughout the book.

My 6 year old son enjoyed the colorful pages and short lessons. With the short lessons, he was eager to do several pages at a time. He was able to understand concepts with little directions. He did have a little trouble with the reading of number words, but that was only a couple of pages in the beginning.

The authors of the book state that the activities in the book are written to the standards of the National Council of Teachers of Mathematics.
