Achievement Indicator:
Regroup 12 tens by trading 
10 tens for 1 hundred
Model 6 x 20 as 6 groups of 20
6 x 20 = 6 x 2 tens
= 12 tens or 120
6 x 2 tens = 12 tens
= 1 hundred, 2 tens
= 120

recall of multiplication and 
related division facts to 9 x 9.

Performance
• Facto - 
Create Facto cards [4 x 5] with squares containing two 
factors, one of which is a multiple of 10. Each pair of students is 
given one grid and a set of product cards with the answers to the 
problems on the grid. Turn the product cards face down. Students 
take turns turning over product cards and placing them on the 
appropriate problem on the Facto card. The first student to achieve a 
straight line wins the game.

Pencil and Paper
• Ask students: What basic fact can be used to find the product
4 x 8 000? What is the product?
(5N4.1)
• Ask students to complete each column and explain the pattern they 
see.
3 x 7 = ___ 4 x 5 = ___
3 x 70 = ___ 4 x 50 = ___
3 x 700 = ___ 4 x 500 = ___
3 x 7 000 = ___ 4 x 5 000 = ___
3 x 70 000 = ___ 4 x 50 000 = ___ (5N4.1)
• Ask students to choose two factors from the list for each estimated 
product. Each number may be used more than once.
