Went over problem solving againUnderstand the problem Devise a plan (trial and error, make a table, picture, diagram)Carry out the plan ( be patient) Look back and reflect (Does It make sense) Solved problems that required different combinations Went over the handshake problemWent over the problem with stampsWent over the problem with basketball teams

Numberation systems Base 10 or a decimal systems Expanded notation373 300 + 70 + 23x100 = 7x10 + 2x1 digits used: 0,1,2,3,4,5,6,7,8,9 Base-10/Decimalused in schools and daily lifeconsistent one to ten relationship between the digits in base-10EX: ten units make a ten, Ten tens make 100

went over base numbers Base 10: ones 10^0tens 10^1hundreds 10^2 thousands 10^3Base 5ones 5^0fives 5^125s 5 ^2125s 5^3 Base 3 ones 3^0threes 3^1nines 3^227s ^5

went over homework number 2 and did mind map

Four operationsAddition: putting togetherIdentity property: A + O = ACommunitive Property (Order Property): when adding two numbers together the order doesn't matter. a+b=b+a 3+4 = 4+3Associative Property (Grouping): when adding numbers the grouping does not matter.(a+b)+c= a+(b+c)Subtraction (Take Away) ComparisonMissing Addend ________________________________________________________________Multiplication (Repeated Addition) 2+2+2 = 3x2 Identity: when a number is multiplied by one it will stay the same Ax1 = A, 1x1 = 1 commutative property: when you multiply two numbers together the order doesn't matter. A,BAxB = BxA 3x7 = 7x3 associative property: when multiplying numbers the grouping does not matter (a*b)xc=ax(b*c)Zero Propertyanything multiplied by zero will equal zeroAx0 = 0 3x0 = 0 Array How many numbers will go into a group Distributive property A x (B+C) = (AxB) + (AxC)
