In the fourth grade, students focus on multi-digit multiplication and division, learning to use bigger numbers, solving multi-step word problems that involve several operations, and they get started in studying fractions and decimals. This is of course accompanied by studies in geometry and measuring.The year starts out with a review of addition and subtraction, patterns, and graphs. We illustrate word problems with bar diagrams and study finding missing addends, which teaches algebraic thinking. Children also learn addition and subtraction terminology, the order of operations, and statistical graphs.
Next come large numbersup to millions, and the place value concept. At first the student reviews thousands and some mental math with them. Next are presented numbers up to one million, calculations with them, the concept of place value and comparing. In the end of the chapter we find out more about millions and an introduction to multiples of 10, 100, and 1000.
The third chapter is all about multiplication. After briefly reviewing the concept and the times tables, the focus is on learning multi-digit multiplication (multiplication algorithm). The children also learn why it works when they multiply in parts. We also study the order of operations again, touch on proportional reasoning, and do more money and change related word problems.
The last chapter in part A is about time, temperature, length, weight, and volume. Students will learn to solve more complex problems using various measuring units and to convert between measuring units.
In part B, we first study division. The focus is on learning long division and using division in word problems. In geometry, we first review area and perimeter, and then concentrate on the topic of angles. Students measure and draw angles, solve simple angle problems, and classify triangles according to their angles. They also study parallel and perpendicular lines.
Fractions and decimals are presented last in the school year. These two chapters practice only some of the basic operations with fractions and decimals. The focus is still on conceptual understanding and on building a good foundation towards 5th grade math, where fractions and decimals will be in focus.

Not durable
Color: Nude, Size: Women 9-13
Only used two of them so far. One sock lasted nearly 3 wears. The other broke before I could finish wearing it the second time. Basically useless junk.

Thick Silicone Moisturizing Socks
Color: Nude, Size: Women 9-13, Color: Nude, Size: Women 9-13
★★★★☆ Thick Silicone Moisturizing Socks
I ordered these silicone moisturizing socks to try for dry heels. Unlike typical fabric spa socks, these are made entirely of soft silicone and are noticeably thicker and very stretchy.
When I first took them out of the package there was a visible fold line in the silicone. It appears to be from how they were folded in the packaging rather than a defect in the material. The silicone itself feels durable and flexible.
The design works like a full silicone sleeve that traps moisturizer against your skin. I applied Aquaphor first and then slid these on so the moisture stays in contact with the skin longer. One thing I noticed right away is that the silicone feels cool when you first put them on, which is actually pretty comfortable.
The bottoms have a zig-zag textured pattern that gives some grip if you need to stand briefly, though these seem better for relaxing while moisturizer absorbs rather than walking around much.
The ankle opening is the tightest part of the sock. It stretches, but it’s noticeably snug compared to the rest of the silicone, which helps keep them from sliding off.
For sizing reference, I wear a women’s 7.5–8 shoe and the size Large fits comfortably. There’s plenty of stretch and I can wiggle my toes easily, so they should accommodate larger feet as well.
They’re also easy to clean. After using them you can simply wash them with soap and water and let them dry completely before storing or using them again.
Overall these appear well made with thick silicone and plenty of stretch. If you use moisturizing socks or heel treatments, these work well for keeping lotion in place while your feet absorb it.
Since this set comes with two pairs for about $10, the price seems pretty reasonable for something reusable like this.

Perfect Training Treat for Dogs with Allergies! 🐾✨
Flavor Name: Rabbit, Size: 4 Ounce (Pack of 1)
The Pupford Freeze Dried Training Treats have been an absolute game-changer for my dog with allergies. Finding a safe, delicious treat that doesn’t upset his system has always been a challenge, but these are perfect!
Made with just two simple ingredients, these treats are not only allergy-friendly but also super convenient. The small size is ideal for training sessions, and my dog absolutely loves them! Unlike some other treats, they don’t have an overwhelming smell, which is a huge plus for me.
If your dog has dietary sensitivities or you’re just looking for a healthy, easy-to-use training treat, I can’t recommend these enough. They’ve made training sessions so much easier and more enjoyable for both of us! 🐶💖🐇

Low calorie and great for dog training
Flavor Name: Rabbit, Size: 4 Ounce (Pack of 3), Flavor Name: Rabbit, Size: 4 Ounce (Pack of 3)
A trainer recommended these for training and our dog loves the taste. They are small and easily handled. There are some larger/longer pieces that can easily be broken in half. With these I am not worried about her spoiling her dinner or gaining extra weight. They don't have much of a smell and being dry, my hands stay relatively clean. She has no problem chewing them as the texture is firm but soft being freeze dried. It can be easy to go through them quickly which made buying the three pack an easy decision.
