Buying a Car and Buying a House. Update: 11/12-11/16

We rely on strategy as opposed to guesswork. 

Greetings 5V Math Families!

Buying a car involves every basic computational component: addition, subtraction, multiplication, and division. Last week, the kids began the purchase process and quickly found that after calculating sales tax and interest, buying a car is not as easy and simple as it appears.

Recap of standards addressed last week: 

-Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. (6.NS.3)

-Fluently divid multi-digit numbers using the standard algorithm. (6.NS.2)

-Interpret and compute quotients of fractions and solve word problems. (6.NS.1)


This week's standards focus: 

-Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. (6.NS.3)

-Fluently divid multi-digit numbers using the standard algorithm. (6.NS.2)

-Explain patterns in the numbers of zeros of the product when multiplying a number by owes of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. use whole-number exponents to denote powers of 10. (5.NBT.2)

Transfer of Knowledge: 

-Continue process of buying a car.

-Calculating sales tax

-Calculating interest

-Determining monthly payment

-Debiting amounts from checkbook

-Crediting checking account

-Debiting and crediting savings account

-Begin purchase inquiry into a home

-Space exploration and distance

Review of Mathematical Practices: 

We try to incorporate each of these practices during the math week.
