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 problem solving with words, to practising fractions, 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.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.

Hallelujah… finally, I found the right pillow!!!
Size: Queen (Pack of 1), Color: White
I have spent a lot of money searching for the right pillow. I recently tried to Tempur-pedic that cost twice with this pillow cost. Tempur-pedic flattened out. I’ve had this pill for a few weeks now and it works wonders. I am a paraplegic. You can have a lot of neck problems. I love the fact that this pillow is adjustable. I immediately saw it was too stuffy and took a bunch out. It works perfect so glad I didn’t spend money on a $200 purple pillow.
I read a lot of reviews and there were a lot of complaints about the odor. Mine did smell funny when it came out of the box. I immediately threw it in the dryer with a few bounce fabric sheets came out smelling fine.
Pillows are a very individual thing, but I think for 40 bucks this pillow is worth a try. I’m really enjoying mine about one of those silk pillowcases to go over it and it sleeps cool and comfortable. Best wishes in your search for the right pillow.
Update: I’ve been using this pillow several months and it continues. Give me a good night rest pain-free.. well worth the money.
UPDATE: I have been using this pillow for three months and it still works great. It does not flat out or get hot..

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes
