Ways to write numbers Standard form: 1,235
Expanded form: 1, Word form: one thousand two hundred thirty five Model form:
4
Your turn: 1,498 Standard form: _____________
Expanded form: ________________ Word form: ____________________________ Model form:
5
1, 8 7 9, 2 6 5 Place Value millions Hundred -thousands Ten-thousands
hundreds tens ones
6
Write the number that has…
1 in the thousands place 6 in the hundreds place 0 in the tens place 5 in the ones place How do you say this number?
7
Even or Odd? LOOK AT THE ONES PLACE!!!!!!
Even = 0, 2, 4, 6, 8, in the ones place example: 2,348 Odd = 1, 3, 5, 7, 9 in the ones place example: 89,573
8
Even or Odd? 61
9
Even or Odd? 1,908,372
10
Even or Odd? 210
11
Comparing Numbers > < += Always line up place value to compare
Look at the biggest place value first 3,456 3,465 So 3,456 < 3,4654
12
> < = ? 45,782 _____45,800
13
> < = ? 894 _____3,764
14
Ordering Numbers ALWAYS READ THE QUESTION UNTIL YOU UNDERSTAND IT!!!
Least to greatest, most to least, largest to smallest, etc… Use process of elimination!
15
Put the numbers in order from greatest to least.
, ,483
16
Fractions 3 = part (how many parts/pieces are being looked at) ___ 4 = whole (how many EQUAL parts its broken into or how many pieces in a set)
17
Write the fraction:
18
What fraction are white?
Write the fraction: What fraction are white?
19
Draw a circle. Show ½ shaded.
20
Draw 9 circles. Shade in 2/9 of them.
21
Money: Counting Coins Always start with the largest coin and then count towards the smallest
22
How much money?
23
Compare the money: > < or ? Ninety five cents _____ Q Q D D D N P P P
24
- $3.48 Money: Making Change A toy costs $3.48 and you pay with $5
$5.00 - $3.48
25
Money: Making Change A bag of candy costs $2.76 and you pay with $5
What is the change?
