Answers are free when you scan the QR code on the back.
Excellent books, have used them for many years in my career as a primary school teacher. Don't waste money buying a hard-copy of the answers, you just need to scan the QR code on the back of the book when it comes and it takes you to Scofield and Sims own, free resources webpage where you can download the answers (and many other things) for free!

Helps to improve maths skills
This Mental Arithmetic book helps us to improve my son's maths skills. But also, I can easily see that he is faster in maths now. The only thing is that we did not buy the answer book, so I am checking his answers. But easy for me to do, so no need to purchase extra for just answers.

great practice book
I bought the Mental Arithmetic series for my daughter. A friend recommended it to me, and Iโm glad I gave it a try. The book offers a wide variety of exercises, which really keeps things engaging. My daughter started from Book 1 and has now progressed to Book 3. Itโs been amazing to see her noticeable improvement. Highly recommend.

All time favourite book
I have been using for my kids for 11 plus. Only drawback is that we have to buy separate answer book that is more expensive than original book.
