-
use mental and written strategies to multiply three- and four-digit numbers by one-digit numbers, including:
− multiplying the thousands, then the hundreds, then the tens and then the ones, eg
− using an area model, eg 684 × 5
Interactive Area Model Tutorial
Area Model Tutorial - Slides 5 and 6
− using the formal algorithm, eg 432 × 5
-
use mental and written strategies to multiply two- and three-digit numbers by two-digit numbers, including:
− using an area model for two-digit by two-digit multiplication, eg 25 × 26
− factorising the numbers, eg 12 × 25 = 3 × 4 × 25 = 3 × 100 = 300
− using the extended form (long multiplication) of the formal algorithm, eg
-
use digital technologies to multiply numbers of up to four digits
* check answers to mental calculations using digital technologies (Problem Solving)
CONTENT
Students:
Solve problems involving multiplication of large numbers by one- or two-digit numbers using efficient mental and written strategies and appropriate digital technologies (ACMNA100)
OUTCOMES
A student:
› describes and represents mathematical situations in a variety of ways using mathematical terminology and some conventions MA3-1WM
› selects and applies appropriate problem-solving strategies, including the use of digital technologies, in undertaking investigations MA3-2WM
› gives a valid reason for supporting one possible solution over another MA3-3WM
› selects and applies appropriate strategies for multiplication and division, and applies the order of operations to calculations involving more than one operation MA3-6NA
Multiplication and Division 1
** NOTE - Covering many of the pointers below to achieve outcomes is dependent on the focus of instruction. As such many of the activities below can be used for a variety of purposes, or to cover a range of pointers. I have therefore grouped them rather than repeating them. Instead, where I have been able to find them, I have listed instructional links below pointers where they are specifically applicable.
Worksheets – whilst the site is designed to share interactive site links, I have included a few worksheet sites as their display could be used on Interactive White Boards or individual computers as practise activities without the need for printing - please see the Stage 3 Home Page.
