Absolutely love this! An absolute must! If you only want to get one book for practice, I would suggest this one. The child has to use the skills that he’s learned to figure out each problem. It really is a lot of fun for both the teacher and the student. Highly suggest!

Challenge problems truly challenging.

This is great extra practice if your student has an easy time with the regular workbook. Much more challenging then the workbook. My son who loves math really enjoyed the challenge. I would not use for a student that just needs reinforcement of the lesson.

I have used both Saxon and Singapore for first grade math and much prefer Singapore although we will continue doing some parts of Saxon However we did find the Singapore textbook and workbook need to be supplemented with extra problems about halfway through (when students are starting to do addition with numbers up to 20) The Extra Practice problems are good; there are just not enough of them That's why I ordered the intensive practice books also I would not recommend the Challenging Word Problems books which I feel are misnamed - at least at the 1 level They are wordy but not challenging For the most part the student need not read the problem If he sees a 7 and a 2 in the section on addition he knows the answer is 9 and in the subtraction section 5 without reading the problem In other words they aren't really word problems just arithmetic drills with references to kids' names and papayas tops and other countable objects
