Lesson 1-2
10
Objective/ I can… I can… Estimate with whole numbers Homework: Worksheet 1-2 and puzzle 1-2
11
New Vocabulary Compatible numbers: Numbers that are easy to compute mentally
12
Examples and Notes Estimate by rounding (nearest 10 or 100): 37 + 62 + 48 40 + 60 + 50 ≈ 150 121-82 120 -80≈ 40
13
Compatible Numbers (use mainly for x and ÷): 38÷6 36 ÷6 ≈6 47 ÷8 48÷8≈6 29×41 30×40≈1,200 2×3,978 2×4,000 ≈8,000

Objective/ I can… I can… Read, write and round decimals Homework: Worksheet 1-5, P.24 #4-32 evens
30
New Vocabulary Expanded form: A sum that shows the place value of each number Ex: standard form 0.75 Expanded form 0.7 + 0.05 Ex: standard form 1.601 Expanded form 1 + 0.6 + 0.001
31
Place value (right of the decimal) HundredsOnes.TenthshundrethsthousandthsTen thousandths Hundred thousandthsMillionthsTen millionthsHundred millionthsbillionthsTen BillionthsHundred billionths Trillionths
32
Examples and Notes Ex: 2.65 Read the place value word for the last number The 5 is in the hundredths place so, Two and Sixty Five hundredths
33
Ex: 13.841 Read the place value word for the last number The 1 is in the thousandths place so, Thirteen AND eight hundred for one thousandths
34
Examples and Notes Ex: 9.04 Read the place value word for the last number The 4 is in the hundredths place so, Nine and four hundedths
35
Examples and Notes Rounding Decimals – Same as rounding whole numbers Underline the place value you’re rounding to. Look next door, 0-4 to the floor, 5-9 climb the vine!

40
New Vocabulary Annex: to add a zero at the end of a decimal number Ex: 0.3 (three tenths) Ex: 0.30 (thirty hundredths) Does not change the value of the number (0.3 = 0.30)
41
Examples and Notes Use a model to compare 0.4 and 0.36 0.4________0.36
42
Examples and Notes An easier way… Annex zeros Order from least to greatest 0.5 0.61 0.07 0.312 Answer:
