FOR 3RD GRADE

NUMBERS AND OPERATION & ALGEBRA are common core content. Common core content means it touches K-12 students.

The State expected 3rd grade students to use their previous knowledge in subtraction to solve number sequence problem. Also to have pre-algebra exposure by learning how to analyze a problem situation, determine the question(s) to be answered, and determine how to represent the problem. For example learning to discover the mathematical rule in number sequence.

Pre-Algebra and Algebra is very important concept because Algebra equates or connect the physical things by discovering its pattern, relationship, association and finally create general rule, general equation or general theory without touching the physical things. Why is this important? Algebra is important because once the relationship or formula or equation was discovered it can be used to precisely do actual financial or physical transaction. Material waste and financial waste are eliminated by not doing trial and error.

How to discover the rule of numerical sequence.

71 - 62 = 9 common number to subtract to find the next third term.

62- 9 = 53 Is this third term? If true the rule is subtract nine from the previous term to find the next fourth term

53 - 9 = 44 Is this fourth term? If true the rule is subtract nine from previous term to find the next fifth term

44 - 9 = 35 is the missing fifth term. If true the rule is subtract nine from previous term to find the next sixth term

35 - 9 = 26 is the missing sixth term.

SO THE ANSWER IS : A 35, 26
