Spectrum Critical Thinking for Math, Grade 4

I love that at the beginning of each lesson everything is thoroughly explained. Every lessons always starts with an example so the student can easily understand what to do. There are a diversity of lessons in the book which helps keep the student engaged. This book teaches different techniques and was a good preparation for my son who's going to fourth grade in the fall.

The book came in excellent condition and the service was very quick! Spectrum mostly always has awesome books for teachers and here is just another one. Lots of works for students to discover and the exercises are extremely relevant to what I am trying to teach. The exercise are not trying to trick students but allows them to understand and dig in more depth! I would totally order again!

I found on answer key page 32 the snswer to question 1 it 810 blue pens instead of 9,258 paper clips!

I like the concepts of this workbook. However, on page 32 problem 1, the question is about paperclips (not blue pens). The total paperclips would be 9,258. The answer they gave was 810 blue pens.

Great summer review to catch up for next year after struggling in 4th grade math
