Math Applet Review 2

 https://www.nctm.org/Classroom-Resources/Illuminations/Interactives/Coin-Box/ 

The second app I decided to review is also from the Illuminations (NCTM) website and is called Coin Box. This game is designed for PreK through 5th grade and the objective is to learn how to count, collect, exchange, and make change for coins and works best on tablets and laptops. The easiest level of the game shows a small collection of coins and asks you to determine the total value. One unique feature of this app is that you can drag coins into a box on the side and then choose which larger value coin is equal to it. For example, I put two nickels into the box on the side and chose to exchange them for one dime. This is a great strategy to help students count if it is easier for them to count by 10s or 25s than 1s, 5s, 10s, and 25s. The second level of this game asks you to collect a certain amount of coins. It asked me to collect 73 cents so I added two quarters, two dimes, and three pennies to the center of the screen. The next level asks you to exchange the coins on the screen for the least amount of coins. The last two levels allow students to make change from coins and then make change from a given value. I like how this app uses differentiation for students who are working at different levels as well as scaffolding so students can work on counting coins, then collecting, then exchanging, etc. Another benefit of this app is that students can work on it independently or the class could play together on a smartboard and make it a game. The teacher could even divide the class into teams and they could take turns and see who gets the most problems right. I enjoyed this app and don’t see any challenges with it!

Manipulatives

  Using manipulatives in elementary mathematics is extremely important for students to gain a conceptual understanding of a variety of mathematical topics. It can be difficult for teachers to determine if students can transfer their understanding from manipulatives to other situations but this is why teachers need to plan time to have students learn the concepts with the manipulatives and then give the students time to solve the problems and only use manipulatives to check their work before finally removing the manipulatives and assessing the student’s knowledge because they won’t usually have these manipulatives in higher grades and outside of the classroom. In order to assess this growth and understanding, teacher observation and questioning are crucial. Teachers need to walk around the classroom or pull individual students or small groups and have students demonstrate their thinking with and without manipulatives. Manipulatives are also great because they help students improve their

Ch 4: Build Procedural Fluency from Conceptual Understanding

A conceptual understanding of math is essential for students to be successful in math classes throughout their life. To me, conceptual understanding is the basics of math (addition, subtraction, multiplication, division, equalities, etc), why these concepts work, how they work together, and then being able to remember and draw from these concepts in more complex problems. In order for students to gather conceptual understanding, they need to be willing and ready to learn and they also need to believe in themselves and their intelligence. The teacher's role is to be the expert but to guide students toward these understandings and not simply state them like facts, or else students will memorize them and not understand why these concepts work and why they are important in the future.  Procedural fluency is the ability to use equations, representations, manipulatives, etc to solve a simple problem. The word simple is relative to the child’s grade level and also their academic level. Fo
