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?

Uses same battery as the rest of my equipment
Size: 8" Edger New
Since I already have and like the Greenworks mower, string trimmer and blower it only made sense to get the edger. Even better that I didn’t need to buy more batteries. I tried another name brand electric edger and returned it for not holding a charge. This one works great! There’s charge left in the battery after everything has been edged. I was concerned how easy it would be to control but fell in love with it first time I used it. To use just pop the battery in, flip the thumb lever, squeeze and edge. Not as noisy as gas powered equipment and no cords to pull. Feels sturdy in my hands and a good weight that’s enough to not pop up if it hits something but not too much to be heavy to carry back to the shed.

First use was great!
I've used it just the one time today. I had previously "edged" with a string weedwhacker, so while the grass was cut back some, there wasn't a trench dug out. I did a gentle push and pull, taking on about 18" at a time to get a new trench dug next to the sidewalk edge. It did a great job! The entire unit was much heavier and sturdy looking than I was afraid it would be for the price, so pleasantly surprised. Assembly wasn't complicated, but it did take two of us to hold it steady because getting the screws to seat in the square hole and not have the cord in the way was a bit tricky. I'm a 70+ lady, not large and not athletic, but I was able to handle this edger with ease. Now, to see how long it lasts!

Great Yard Helper!
So easy to use and affordable! This edger is a great time saver, easy to operate, and relatively easy to adjust although you may need a pliers or screwdriver to help with the adjustment levels, but its not difficult. I would have given this 5 stars but just one thing that is a sticking point for me is I wish this had its own stand or hanger because of its odd shape, it doesn't necessarily balance upright too well. It’s long and the guide wheel in the front sticks out. So, it is always awkward to get it tidy in the garage when not in use. Now maybe this is what it's like for landscapers…I’m not a professional. Just a homeowner doing my own upkeep. With what this costs, I’ll figure it out, and is worth the money.
