Calculators are very useful in learning algebra. Calculators range in complication, from simple to scientific. Scientific calculators can carry out in-depth algebraic expressions, while some simple calculators can only perform basic functions, such as multiplication, division, addition and subtraction. To use calculators in a classroom, the teacher must first decide what a calculator should do for the student. Whether it is finding the answer to a complex math problem or just aiding in basic math, the students must be given guidelines for purchasing a calculator that can be used at school.
The abacus may be one of the first calculation props used in algebra. The first abacus was nearly just lines sketched in sand, and rocks lying along those lines. The abacus used today consists of a frame with wires and beads and is easy to master. To use the abacus, simply slide the beads over to one side, depending on the numbers in the algebra problem. Then count the total amount of beads on one side to find the answer to the algebra problem.
Algebra tiles are useful in a math class. Each tile represents a monomial. The monomials are used together to create an algebraic expression. Algebra tiles are useful for visual learners, since the tiles can be looked at physically and linked to algebra problems. The tiles can represent algebraic expressions, such as multiplication, division, addition and subtraction. Although the problems still need to be solved mentally, the tiles provide visual reassurance to the solution of the problem.
Napier's rods were named after John Napier, a man devoted to simplifying complicated algebraic expressions. Napier created a table consisting of numbers and multiples. Each number in a multiplication problem containing large numbers can be laid out on the table. Once the numbers are in place, simple addition is used to find the answer to the complex multiplication problems. Although a lesson needs to be taught to children on how to use the table, students will be able to execute it properly with some practice.
