Lesson 1-2

Objective/ I can… I can… Estimate with whole numbers Homework: Worksheet 1-2 and puzzle 1-2

New Vocabulary Compatible numbers: Numbers that are easy to compute mentally

Examples and Notes Estimate by rounding (nearest 10 or 100): ≈ ≈ 40

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

Lesson 1-5

Objective/ I can… I can… Read, write and round decimals Homework: Worksheet 1-5, P.24 #4-32 evens

New Vocabulary Expanded form: A sum that shows the place value of each number Ex: standard form 0.75 Expanded form Ex: standard form Expanded form

Place value (right of the decimal) HundredsOnes.TenthshundrethsthousandthsTen thousandths Hundred thousandthsMillionthsTen millionthsHundred millionthsbillionthsTen BillionthsHundred billionths Trillionths

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

Ex: Read the place value word for the last number The 1 is in the thousandths place so, Thirteen AND eight hundred for one thousandths

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

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!

Examples and Notes Round to the nearest hundredth Round to the nearest tenth
