Measure and compare objects in standard units.
Understand equivalent measurements.
Conversion, Equivalent, Inches, Feet, Yards, Cups, Pints, Quarts
1. Students used a measurement conversion chart to find equivalent measurements (inches to feet, feet to inches, cups to pints, pints to quarts, pints to cups, quarts to cups, etc.)
2. Students played game called, "Memory Match." Students flipped cards over and tried to find equivalent measurement matches (inches, feet, yards).
1. How may inches are there in 7 ft.?
2. How many cups in 4 quarts?
12 in.= 1 ft.
2 c. = 1 pint
2 pints= 1quart
1. 84 inches
2. 16 cups
Use place-value understandings to round whole numbers to the nearest ten or 100.
Use understanding of how to round two-digit numbers and expand the strategy to three-digit numbers.
Understand that rounding identifies the multiple of 10 or 100 that is closest to the given number.
Understand that the previous place (one place smaller) is the key digit to evaluate to determine whether a number is rounded up or down.
Tens, Hundreds, Round, Place Value,
1. Students filled out a number line and used it as a guide to round a number to the nearest 10 and then 100.
2. Students rolled a die to create a two-digit and three-digit number. They used their knowledge to round to the nearest 10 and 100.
3. Students were given a large number on a whiteboard. After looking at their number, students used their rounding knowledge to round to nearest 10 and 100.
1. Round 1, 276 to the nearest ten and nearest hundred.
2. Round 988 to the nearest ten and nearest hundred.
3. What is the rule about rounding?
1. Nearest 10= 1,280 Nearest 100= 1,300
2. Nearest 10= 990 Nearest 100= 1,000
3. If the number is 5 or higher, round to next higher number. If the number is 4 or lower, keep it the same. All numbers before the rounding number are left alone and stays the same.
