Numbers to 100 000 Student Outcome: I can describe numbers to 100 000
More on Place Value Large whole numbers are arranged in groups of threes called periods. Each period has a hundred(s), ten(s) and one(s) position. See the number below as an example. The 8 is in the tens position, the 5 is in the ten-thousands position.

Challenge Information
Student Outcome: I can describe numbers less than 0 Decimal numbers are also arranged in groups of threes called periods. Each period has a ten(th), hundred(th) and thousand(th) position. See the number below as an example. The 2 is in the hundredths position, the 5 is in the hundred-millionths position.

Representing Numbers Student Outcome: I can describe whole numbers in different ways Place the digit in the proper place value cell to complete the number. 652 89 045

Representing Numbers Standard Form Shows the written number 3 864
Student Outcome: I can describe whole numbers in different ways Standard Form Shows the written number 3 864 Expanded Form Shows a number as a sum of the values of its digits (3x1000) + (8x100) + (6x10) + (4x1)

Representing Numbers Student Outcome: I can describe whole numbers in different ways Show these numbers using expanded form 652 89 045

Representing Numbers Student Outcome: I can describe whole numbers in different ways Example In the number 1 329: the one is in the thousands position the three is in the hundreds position the two is in the tens position the nine is in the ones position.

Estimating Sums How can you find the answer to 459 + 201 =
Student Outcome: I can use different ways to estimate when adding How can you find the answer to = Front – End Rounding Using the first digit from each number to get an estimate Compatible Numbers Using multiples of 10, to make a number easier to add Compensation Rounding a number up then the next number down

Estimating Sums Front – End Rounding
Student Outcome: I can use different ways to estimate when adding Front – End Rounding Using the first digit from each number to get an estimate Examples: = = (first digit in each number) = = 72 x 23 = 70 x 20 = 1400 =

Estimating Sums Compatible Numbers
Student Outcome: I can use different ways to estimate when adding Compatible Numbers Using multiples of 10,100 to make a number easier to add Examples: = = (multiples of 10) 27 x 41 = 30 x 40 = (multiples of 10) = = (multiples of 100) =

Estimating Sums Compensation Rounding a number up then the next down
Student Outcome: I can use different ways to estimate when adding Compensation Rounding a number up then the next down Example: = = (down) (up) (down) (up) = =

Using Benchmarks to Estimate
Student Outcome: I can use benchmarks of 10’s, 100’s, 1000’s, ’s Benchmark Definition A benchmark is something (for example a number) that serves as a reference to which something else (another number) may be compared. The most common use for benchmarks is in estimation. Example: Is 258 closer to 250 or 260? Is 258 closer to 200 or 300? Is closer to or ? Is closer to or ?

Using Benchmarks to Estimate
Student Outcome: I can use benchmarks of 10’s, 100’s, 1000’s, ’s Medicine Hat’s Population 2009 61,097 What kind of benchmark would you use to describe Medicine Hat’s Population? Medicine Hat’s Population for the year 2009 is ……………..?

Estimating Differences
Student Outcome: I can use different ways to estimate when subtracting How can you find the answer to = Front – End Rounding Using the first digit from each number to get an estimate Compatible Numbers Using multiples of 10, to make a number easier to add Compensation Rounding a number up then the next number down

Estimating Differences
Student Outcome: I can use different ways to estimate when subtracting How can you find the answer to = Front – End Rounding Using the first digit from each number to get an estimate = 1 000 OR Look at the last 3 digits of each number (to be more accurate) = = = 1 700

Estimating Differences
