In one sentence, describe what the following article is about: Mood rings are accessories that have a thermochromic element that changes color based on temperature. The color of the ring supposedly suggested the mood of the wearer. Select a mood ring in a style you like, such as a large circle, butterfly, or dolphin shape.  While these are mainly popular with girls, mood rings are a unisex accessory. The mood ring was invented in the 1970s, but it did not get widely popular until the early 90s. A slap bracelet consists of a flexible piece of steel covered in fabric, silicone, or plastic. To wear, lightly slap the band on your wrist, and the metal effortlessly coils around your hand. Pair these with your tube tops and leggings, for instance. Slap bracelets came in many colors, patterns, and textures, such as animal print, zig-zags, and polka dots. Small, silver hoop earrings grew popular due to many television actors wearing them. You can wear 1 hoop in each ear, for instance. If you have multiple ear piercings, wear a larger pair in the first hole and a smaller pair in the second. You can also opt for gold or black hoops. Before the 90s, body piercings were not very popular. The grunge scene helped spread the piercing trend, and soon many teens rocked a pierced nose, eyebrow, lips, and nipples. If you want an authentic 90s look, consider getting a piercing. Keep in mind that piercings are semi-permanent. 90s hip hop encouraged many people to wear snapback hats. Pick a hat with your favorite sports team or band logo, and put it on after you finish getting dressed. For a true 90s style, turn the brim of the hat around so it faces your back.  Snapbacks are known by their large, flat brim. They also have an adjustable strap consisting of 2 pieces of plastic. You can wear a snapback with your Coogi sweater and baggy jeans for a hip-hop look. Studs were all the rage in the 90s grunge scene, and many people wore studded belts with band shirts and flannels. In addition, studded belts were very popular with baggy jeans. Pick a belt with silver, red, blue, or pink studs, for instance. You can also get studded chokers or jackets for a grunge or punk look. Kangaroos are a brand of sneaker known for their bright colors and small, zip-up pocket. Timberland boots grew widely popular with the hip hop scene. Doc Martens are a combat boot style that was popular with grunge music. Pick your favorite style, and rock your footwear with your 90s look!  For example, wear Kangaroos with your bike shorts. Pair your Timberlands with baggy jeans and a Coogi sweater. Rock your Docs with a flannel shirt and studded belt.
Summary: Wear a mood ring to showcase a 90s staple. Strap on a slap bracelet to add color and pattern to your outfit. Put in a hoop earring if you have pierced ears. Get a body piercing if you want to follow a 90s trend. Put on a snapback hat for a popular 90s accessory. Wear a studded belt to add a touch of grunge to your outfit. Choose shoes from brands like Kangaroos, Timberland, or Doc Martens.

Problem: Article: Children respond well to visual tools that help them understand addition concepts.  Any easily handled object may be used, from beads or blocks to Cheerios.  Start with a small number of items and use a variety of tactics to demonstrate number relationships:  Give the child two small groups of items -- say, a group of two blocks and a group of three blocks.  Have the child count the number of blocks in each group. Have the child combine these two groups of objects and count the total number of blocks.  Explain that he or she has "added" these groups together.  Provide a set number of objects -- six Cheerios, for example -- and ask your child how many ways he or she can combine groups of Cheerios to make six.  She might create one group of five Cheerios, for example, and one group of one.  Demonstrate how you can "add" to a group of objects by stacking.  Start with a stack of three pennies, for example, and add two more to the stack.  Ask your child to count how many pennies are now in the stack. "  In a classroom setting, take advantage of your young students' need to move around regularly by using them as human manipulatives.  Utilize tactics similar to those you'd use with objects to group and combine students and have them count themselves in different configurations.  (Stacking students is not recommended!) Use modeling clay to create manipulative objects, or combine your addition lesson with an art lesson in using scissors to create a collection of paper shapes. Dice lend themselves easily to beginning addition games.  Have students roll two dice and practice adding the resulting numbers.  You may also use playing cards or dominoes. When working with groups of students with varying abilities you may tailor this game to provide an extra challenge for quick learners.  Instruct them to add the results of three or more dice or playing cards. Use money to practice adding ones, fives, tens, and even intervals of 25.  This tactic teaches money skills in addition to addition, and has the added benefit of demonstrating the practical advantages of learning addition.
Summary:
Use objects to demonstrate how addition works. Group children and use their bodies as human "manipulatives. Consider having children create their own manipulatives. Employ game pieces in new ways to create addition games. Count with coins.
