Heard of Math Mastery but don’t know where to begin? Don’t worry, DK has got you covered!
Math Mastery is a transformational approach to teaching mathematics that was developed in Singapore and is now used around the world, including in thousands of schools across the US.
Children are taught multiple methods to solve math problems, enabling them to gain a thorough and adaptable understanding of topics, making it easier for them to apply their knowledge to different scenarios. Each topic is studied in depth to develop a secure understanding of math concepts. This leads to greater progress in math learning, as topics are well understood and therefore don’t need to be revised in great detail, meaning each new concept builds on prior learning.
Based on this widely successful approach, this wonderful workbook is full of top tips led by appealing characters who offer useful guidance to parents and children alike with the goal of making learning math both accessible and interesting.
This workbook is part of a new series developed in partnership with the award-winning educational publisher Math — No Problem! The books encourage a deep knowledge of core math concepts without fostering a reliance on memorization or rote learning.
A must-have math book for children aged 9-10 at a Grade 4 level, as well as for adults who wish to become more familiar with math taught in schools, to better support their children at home.
From finding sums to solving world problems, this helpful workbook covers it all while incorporating an inclusive approach which builds self-confidence so that no child feels they ‘can’t do math’.
At DK, we believe in the power of discovery.
So why not explore the rest of the workbooks in our Math — No Problem! Master Math At Home series? Each workbook can be bought individually or as part of a collection, specifically targeted to early learners aged 9-10 at a Grade 4 level. Multiply like a magician with Math — No Problem!

Amazing
Size: 7.5-8.5 Women/6-7 Men, Color: Khaki
These slides are so good! First off, the price is insanely good for such great, long lasting slippers! I ordered the khaki color and it was a nice tan color that elevates every look, whether comfy or more casual. These are so comfortable and also flexible but without breaking which is amazing! The material is soft and perfect for everyone.

Walking on Pillows!
Size: 9-10 Women/7.5-8.5 Men, Color: Dark Blue
These slides are like walking on pillows! This is my second pair, and I wish I could wear them everywhere. They are beyond comfortable. They also look nice on your feet. They are well-made, and I know they will last a long time. I have had one pair for over a year.

So comfortable
Size: 10.5-11.5 Women/9-10 Men, Color: Black
They're so soft to wear! I needed something to wear when it's hot out. These work great and they feel durable! They also clean up easy if i choose to wear them outside. I bought my daughter a pair as well. I think they fit true to the size. I am a size 7-7 1/2 and ordered 7-8.

Size Up!
Size: 9-10 Women/7.5-8.5 Men, Color: Chocolate, Size: 9-10 Women/7.5-8.5 Men, Color: Chocolate
These are very comfortable! My only issue is that I'm a size 9, so I ordered the womens 9-10 and they are *almost* too small. My heel really wants to come out the back. I know the description says to size up, so you really should lol. They are also narrow, as I have wide feet! I will still wear them, just not if I have to walk too much

No more stubbed toes!
This is a very comfortable slip on shower sandal. The bowl design that makes it protect your toes and feet works like a champ! No more stubed toes !! They wore great to prevent that. And they have great traction in smooth wet surfaces. Even with soap on them.
Comfortable fit..
I would buy this product again. Thanks
