Warm-up

Show 3,847 with base-ten blocks. What is the value of the 3? (3000.) The 8? (800.) The 4? (40.) The 7? (7.) Now: what number is 1,000 more than 3,847? (4,847.) What is 100 less? (3,747.) Quick mental math using place value.

Explore

Multiples investigation: each group explores multiples of a different single-digit number (3, 4, 6, 7, 8, 9) using a hundred chart. Colour all multiples. Describe the pattern. What do you notice about numbers that appear in two groups? (Common multiples.)

Practice

Students represent 6 four-digit numbers in expanded form and with base-ten blocks, list multiples of 4 to 40, and place 8 numbers on a 0-10,000 number line. Exit ticket: what is 1,000 more than 7,843?

TIP Use the thousands cube (10x10x10 block) to make 1,000 tangible. Compare: a thousands cube vs. 10 hundreds flats vs. 100 tens rods vs. 1,000 ones units. All equal 1,000: the landmark of Grade 4 place value.

WORKED EXAMPLES

What is the value of each digit in 5,306?

5 is in the thousands: value 5,000. 3 is in the hundreds: value 300. 0 is in the tens: value 0 (placeholder). 6 is in the ones: value 6. Expanded: 5,000 + 300 + 0 + 6 = 5,306.

List the first 8 multiples of 6.

6, 12, 18, 24, 30, 36, 42, 48. These are also the products in the 6-times table: 6x1 through 6x8.

MATERIALS

•Base-ten blocks (thousands cubes, hundreds flats, tens rods, ones)

•Place value mats to 10,000

•Number lines 0-10,000

•Skip-counting strips for multiples

WATCH FOR

!Students may not write the zero in 5,306 when dictating its digits, producing 536. The zero is a critical placeholder keeping the 3 in the hundreds position.

!Students may confuse multiples with factors. Multiples of 6 are what you get when you multiply 6 by whole numbers. Factors of 6 are numbers that divide 6 evenly.
