We've been discussing "What's My Rule" Function Machines in Math: When you put a number in a function machine, the machine has a rule. For example "+25". So whatever the input number is, it will change the output number accordingly. If "+25" is the rule and 50 went IN, 75 will then come OUT. If 100 went in, 125 comes out, etc.
We've also discussed the use of "*" and "/" as symbols for Multiplication and Division in older grades, as well as for use when typing on the computer.
We've reviewed the meaning of FACTOR (2*10), PRODUCT (20), MULTIPLES (20,40,60), and SQUARE NUMBERS (1*1, 2*2, 3*3, etc).
We discovered that from all 100 Basic Multiplication facts, only 28 really need memorizing! We are now working at getting better with these facts using our Fact Triangles.
