Each of us has encountered someone who has expressed some hesitancy or dread surrounding math or math classes. The Ghost of Mathematics provides teachers, students, and parents alike with tips and strategies for overcoming these anxieties and inhibitions surrounding particular areas and topics in mathematics that are known to trigger math anxieties. We can begin to eliminate math anxiety by building proficiency in mathematics at the elementary school and address math anxiety by building proficiency in mathematics at the early childhood and elementary school levels.

Author and mathematician, Joseph A. Porzio details how to overcome these self-imposed obstacles surrounding learning. School leaders, math coaches, classroom teachers, and even parents must support young students in developing and mastering conceptual understanding; procedural fluency; and, problem solving strategies.

Great product, thoughtful design, great customer service
Color: Black, Size: 40 oz
I don't write a lot of reviews, but I felt like this product deserved one. This is an excellent cold brew maker. It is very easy to use and has a great 1,200 mL capacity. The plastic construction is more versatile (less fragile) than other brewers made from glass. The filtration system eliminates the sludge that other brew systems leave. The packaging is very thoughtful - a scoop and sponge are included. The scoop is easily overlooked, but it is the perfect size to clean the used grounds out of the filter. The sponge is an unexpectedly useful form factor to help with cleaning. Hopefully the sponges can be ordered separately, since sponges don't last forever. Some minor downsides: Cleaning is moderately easy, but the only component that is recommended for the dishwasher is the pitcher (which is also easiest to clean by hand). All of the other elements are recommended for hand washing, which doesn't take long. The way the filter is configured, the pitcher will work most effectively if stored (at least for part of the brew cycle) on its side. However, there is a vent in the lid that is prone to leaking when the pitcher is stored on its side. Brewing upright can lead to the top grounds not getting exposed to water. Unfortunately, one of the pieces broke during routine use after a couple of months: the pitcher lid is attached with a couple of hinges that snap the lid into place on the pitcher. One of the hinge attachments broke. I contacted customer service and a replacement pitcher arrived four days later. I'd recommend being careful with these hinge attachments as they seem prone to break. At the same time, the customer service is very responsive and suggests that they take support of their products seriously.

Nice little cold brew pitcher
Color: Black, Size: 40 oz
Easy to use and very easy to clean. We have made one batch of cold brew so far and are very pleased with the results, the suggested measurements produced a very smooth tasting coffee. Definitely worth trying for the price.

Best cold brew ever
Color: Black, Size: 40 oz
How did I live without this?? My ice coffee made in this is the best I have ever had. It is very easy to use and also very easy to clean. I was very impressed with the quality of the pitcher. It is very thick acrylic and cleans up great with absolutely no staining or discoloration. I am going to be ordering another for my brother! I highly recommend this one!

Very nice but -
Color: Black, Size: 64 oz
Got it today. Just put it to use and made some cold brew. Looks nice and sturdy and doesn’t leak. Has a great large capacity to make a lot of cold brew. Lid closure is great and seals nicely. Very easy to use and user friendly. The plastic material is very thick feeling so that tells me it will withstand quite a bit. I like it so far. My only issue is as soon as I opened the box and pulled the spoon out, it was broken. The bottom stand is completely broken and barely stands up. So that’s disappointing. Otherwise, seems very nice.

Reliable and Easy to Use Cold Brew Coffee Maker
Color: Black, Size: 40 oz, Color: Black, Size: 40 oz
This cold brew maker is easy to use and does the job well. I get smooth coffee every time without bitterness. The size is good and fits in my fridge without taking much space. The filter works well and keeps most of the grounds out of the coffee. Cleaning is simple and does not take much time. The build feels solid for daily use. I like that I can control how strong the coffee is by changing the water and coffee ratio. One thing to know is that you need coarse ground coffee for best results. (I use Bizzy coffee) Letting it steep longer makes the flavor better. It is not insulated, so you should keep it in the fridge while brewing.
