Description
The Relative Numbers presentations give the child a concrete understanding and practice performing operations using relative numbers. Understanding the concept of relative numbers is a pre-requisite for work with exponents, squares, cubes, and algebra. It is an integral component of the math curriculum, which Montessori herself compared to the "tree that supports the parts" for the child's understanding of the concept of numeration.
The pre-requisites for this unit are the Function of the Decimal System and Operations, which can be found here:
Unit 1: Function of the Decimal Numbers System
Unit 2: Applying the Four Operations to Decimal Numbers System
The Bundle for the Function of the Decimal Numbers System can be found here (it includes a video and printable fraction pieces):
Unit 1: Function of the Decimal System BUNDLE
The presentations and command cards in this bundle are used:
- To introduce the child to the concept of negative numbers.
- To take the child’s consciousness the concept that it is possible to add negative and positive quantities.
- To understand that a result of ‘addition’ can be a negative result.
- To use positive and negative bead bars to work out a snake as a sensorial experience.
- To use positive and negative number cards to indicate positive and negative numbers.
- To collect similar terms and show them within one set of parentheses.
- To bring an understanding of the work on relative numbers for algebra work.
- To realize that it is possible to add negative and positive numbers and that the result may be a positive sum, a negative sum, or zero.
- To understand the extracting rule with positive and negative integers.
- To understand the rules of the products of two relative numbers.
- To understand the rules of the quotients of two relative numbers.
- To help further the child's passage to abstraction.
*Fraction circle pieces can be purchased separately in my store here:
Fraction Cut-out Circles for Work with Decimal System and Fractions
This bundle includes:
- Material analysis for the Relative Snake Game
- A series of 8 Presentations
- 15 command cards for the four operations using relative numbers with the answers (control-of-error) on the back
- Detailed step-by-step presentation instructions
- Photographs and Illustrations
- With each material analysis presentation is given the purpose, direct aim(s), indirect aim(s), control of error, and points of consciousness
This unit is useful for children from ages 8-10 years of age and up.
After the Operations (Addition, Multiplication, Subtraction, and Division) with the Relative Numbers unit, the child will be ready for work with Numerical Powers.
