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?

waterproof
This bikini trimmer is a compact, handheld device, roughly the size of a lipstick tube, that operates on a rechargeable battery and comes with a USB charging cable and a protective cap. I have been using this trimmer for a little over a week now as part of my personal grooming routine. I initially picked this item because I was looking for a small, waterproof tool that could be used quickly and efficiently. I appreciate that the body is made out of a smooth, waterproof plastic, which I think makes it easy to clean and feels hygienic for both wet and dry use.

Handy Compact Trimmer
I really like how this trimmer has two functions in one, it makes things super convenient. It’s small and easy to hold, so I can use it on different areas without feeling awkward. I tried it on both legs and underarms, and it gave a smooth finish without irritation. The design makes it easy to switch between trimming and shaving, which is a nice touch. I also appreciate that it’s waterproof, so I can just rinse it clean after using it. Overall, it feels like a simple and practical tool to keep around for quick grooming.

efficiently remove body hair
It is excellent bikini trimmer to trim overgrown hair. Works great and super easy to use. It's easy to handle, charges quickly, and trims without irritation. I like the 2 in 1 dual side design. The round head hair remover works very efficient and after removal of arm hair, I don't feel any pain. And the residue hair could be released from the device easily. Perfect for travel or quick touch-ups at home. Love the cute design and color. It is affordable bikini trimmer that gets the job done without irritation or nicks.

Functional
I used to get cuts when using regular razors but ever since I switched to this electric razor, I no longer have to worry about getting hurt. The blade is extremely sharp yet gentle and provides a smooth shave on my face, legs, underarms and other areas without any pain. The waterproof feature makes cleaning easy. I can simply rinse it under the tap. The rechargeable design is also very convenient. It's small and portable easy to take on business trips and travels! The shaver glides smoothly on underarms and the detailer head gives perfect shaping for bikini lines. Fully waterproof for shower use and the self cleaning blades rinse effortlessly.
