Last week our class started to explore place value. By the end of grade 3, students are expected to be able to do the following:
– represent, compare, and order whole numbers to 1000, using a variety of tools (e.g., base ten materials or drawings of them, number lines with increments of 100 or other appropriate amounts);
– read and print in words whole numbers to one hundred, using meaningful contexts (e.g., books, speed limit signs);
– identify and represent the value of a digit in a number according to its position in the number (e.g., use base ten materials to show that the 3 in 324 represents 3 hundreds);
– compose and decompose three-digit numbers into hundreds, tens, and ones in a variety of ways, using concrete materials (e.g., use base ten materials to decompose 327 into 3 hundreds, 2 tens, and 7 ones, or into 2 hundreds, 12 tens, and 7 ones);
– represent and explain, using concrete materials, the relationship among the numbers 1, 10, 100, and 1000
Beginning this week the class will be given a “Number of the Day”. We will use the number of the day to practice representing numbers in standard form, written form, expanded form and base-ten form. We will also use this number to practice adding and subtracting 10 and 100 using mental math.
Below is a video we watched on place value.
