Humble Math - Double Digit Addition & Subtraction : 100 Days of Practice Problems: Grades 1-3, Word Problems, Reproducible Math Drills

This is wonderful to use with my younger son. Its not stressful because each page is broken up into days, so he knows what to expect each day, and it has made him better at math I think.

He goest through the pages on his own, and really enjoys this book.

I liked the size of the writing font the most. Usually when I buy these kinds of the books the print is quite small and my son (how has yet to care about near, legible print) has a hard time keeping in line with the text of the problems. These books have large enough print for even MY kid to easily write in line with the problems.The book is separated into sections of simpler problems progressing to more difficult ones. Each page gives a small heading so you can easily scan for the level of difficulty. None of the pages are perforated but considering how inexpensive the book is I don't really count that as a downside.

My boy loves this book he love math and lives the challenges! He’s only in 1st but loves big math problems

I took double-digit addition & subtraction and multi-digit multiplication for my kids. I like it overall, but i really think that there is a lot of empty space on these books. Half of the multi digit multiplication book has total of 12 exercises per page and the other half has a total of 8 exercises per page. It is not as intense as the onedigit multiplication and division book. I liked these last ones better. I wished it had more exercises.

Gave plenty of practice in addition and subtraction. Graduating difficulty. It was perfect for us and our student. There's an answer key at the end. I liked there were words problems on each page.

My son really wasn't enjoying some of the online math activities the school recommended while distance learning so I bought this - it was such a great price it was worth a try. I showed the teacher and she approved. Now he does two pages a day for math practice and it's easier than having to get him on a website and find the password. Unlike with the computer it's not timed or stressful, he doesn't fight or get frustrated, he just does the work and it's fine. I would recommend this for supplementing distance learning or keeping kids sharp during the summer.

Got this for my 1st grader to quicken his addition and subtraction.It’s very good. Perhaps it worthwhile to mix it up with another math book with more interest - like bar graphs, fractions, etc…This is purely as it states - addition and subtraction.

Worth price just what I wanted

Not really anything added value about this book. Just bunch of multiplication, very boring

Its good thank you

This is a great workbook. It's very well layed out and clear to read. We did a couple of page of each topic each day when school were closed and it worked very well. My child enjoyed it so much so he'd often do two pages of each topic. We will continue to use this book and I Highly recommend it.

Wasn’t happy with the type of questions
