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 measuring mass to reading graphs, 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!

Absolutely Amazing Mattress Topper – Perfect Fit and Incredible Quality
Color: White, Size: Twin
This mattress topper is truly amazing! It arrived on time and the size was exactly as described—perfect for my bed. From the moment I unboxed it, I could tell the quality was outstanding. It’s so well-made and comfortable that I honestly thought it must be from Macy’s. The topper adds the perfect amount of softness and support, making my bed feel brand new. I was so impressed that I decided to buy a second one: a queen for myself and a twin for my 25-year-old son, and he absolutely loves his as well. Since using this topper, I’ve noticed a huge improvement in how well I sleep—no more tossing and turning or waking up with aches. The materials feel premium, it stays in place on the mattress, and it doesn’t have any weird odors that some toppers have. Honestly, this is one of the best purchases I’ve made in a long time. I would highly recommend this mattress topper to anyone looking for comfort, quality, and a better night’s sleep. It’s a small investment that makes a big difference!

Feels Like Sleeping on a Cloud

The quality is excellent, it stays in place well, and it adds the perfect amount of cushion without feeling too heavy. I wake up feeling more rested and without body soreness. Definitely one of the best purchases I’ve made for better sleep.

Very soft for the thinness. Would buy again if needed
Color: White, Size: Full, Color: White, Size: Full
I bought this four days ago and so far so good. I threw it in the dryer for 40 minutes and it fluffed up very well. I, unfortunately, bought my new full mattress too firm and needed more support. This topper came to be the most affordable option for me and as of now, my partner and I love it so much. It hugs us very well for the padding to be fairly thin. Wish it could be a tad bit thicker but it’s very soft and I can’t wait to lay down after work!

Comfy
Color: Grey, Size: King
It's comfy not as thick as the picture makes it look but definitely improved our sleep after being on a rock hard mattress for so long. It smelt a little funny when first opened it but went away with fluffing it. Fits our king sized mattress perfectly. It's kind of like sleeping on a fluffy comforter.

Wonderful, great finitions
Color: White, Size: Queen, Color: White, Size: Queen
I thought of a size "full" when I ordered a queen size for my French 140cm x 200cm guest bed. When I received the package and realized I had made a mistake, I was despaired because I had no time to change it so I went to look for bed size equivalences between France and USA. At the end, I thought I could give it a try so I did, and I am so happy I did because it perfectly works! I am so relieved. The top mattress is padded, even just coming out of the package. I am still going to let it take its fluffyness for a few hours! 3asy to unpack, to install, to use!!! Easy to wash, easy to dry! I usually wash PADDED top mattresses with a cup of vinegar to sanitize and I always add the necessary amount of laudry powder only on a semi warm cycle. I let the top mattresses dry in the dryer with new zealand woolen balls to increase the fluffy aspect, but always on a soft cycle or with cold air. It takes a bit of time, but it is gentle on the microfiber fabric! This queen top mattress is very comfy and it should please my guess! FYI, if you like to sleep on a hard or firm mattress forget this one, it is very soft!!! It might not be for your back depending on what you suffer from, but suffering from lombalgia, it relieved my pain when I slept on mine, though. Remember just that sleeping well is, among other things, a question of possitions...like on your left side to help your stomack, or on your back. I do not know it it helps to cool down, especially because it Texas at night it is warmmmm! All in all this white padded top mattress seems to be a good quality product. It was a steal being for sale at half price! It fits perfectly thick mattresses too and the elastics are solid. My guests will sleep like angels👍
