- 1. Hundreds: Ten Tens Make a Hundred
Bundle ten tens into one hundred, count in hundreds to 900, read and build three-digit numbers with flats, rods and cubes, and use a zero to hold an empty place.
- 2. Digit Value and Expanded Form
Read three-digit numbers on a place-value chart with counters, find the value of a digit from its place, and write numbers in expanded form, including a zero part and a missing part.
- 3. Number Words to 1,000
Say and build three-digit numbers in words as two chunks, write number words as digits with a zero for a missing part, and build teen and ty words from pieces.
- 4. Ten and Hundred More or Less
Find 10 more, 10 less, 100 more and 100 less by changing one digit, cross a hundred boundary (395 + 10 = 405), and find missing numbers in patterns.
- 5. Number Lines to 1,000
Read the scale of a number line, count in 50s, place numbers on a line with a pin, find halfway between two hundreds, and estimate which two hundreds a number sits between.
- 6. Comparing and Ordering to 1,000
Compare three-digit numbers from the left, use the symbols greater than, less than and equal to, and put numbers in order from least to greatest and back.
- 7. Rounding to the Nearest Ten
Find the two tens a number sits between, use the ones digit to round to the nearest ten, round on a number line, and see how rounding up can change the hundreds.
- 8. Rounding to the Nearest Hundred
Find the two hundreds a number sits between, use the tens digit to round to the nearest hundred, round on a number line, and tell when to look at the ones digit and when to look at the tens digit.
- 9. Thousands: Four-Digit Numbers
See that ten hundreds make a thousand, read and write four-digit numbers on a place-value chart, find the value of a digit, write four-digit numbers in expanded form, and compare and order numbers to 9,999.
