My students need a desktop abacus to practice math fact memorization of numbers 1 through 10, counting to 120, addition and subtraction to 20, and understanding base 10.
My students need practice in understanding number concepts through manipulating objects. They need to practice number concepts through touch first. When the patterns become apparent to them using two color beads, they will be able to recognize and understand math concepts quickly.
My students are primarily from a Hispanic background.
Many of them are trying to acquire English vocabulary while still speaking Spanish at home. Many of them are learning English, but try everyday to be great students and learn the concepts taught. By the end of the year, most of them are reading or beginning to read and understand most of what they read despite language.
My students will be able to count beyond 120 by the end of the year. They will master their math facts from 1-9: example is 1+9=10, 2+8=10, and all of the facts from 10 and below. My students will be able to count using the base 10 model and understand what ones and tens are by using the beads to slide back and forth. They also will be able to add and subtract up to 20 using the desktop abacus. We will be using it everyday as practice. Eventually, they will write their own addition and subtraction problems using the abacus and not doing pencil/paper activities. My hope is that my students are able to attack the common core math for first grade using most concepts on the abacus.
I will be able to teach the students math from the beginning of the year by introducing the abacus as a tool for them.
It will be very clear to them by using it because it is a concrete tool for them. We will not have to waste time passing out manipulatives like bears or blocks and losing them during the lesson. All the manipulatives that they need will be on their desk. They won't be able to lose the pieces. 1st graders are easily distracted, so this will help immensely.
