Rows, Rectangles and Multiplication
Years 4 - 8

 

  • Click the image to start your Picture Puzzle.
  • Say yes to 'Full Screen' when asked.
  • Use 'Esc' to move out of full screen.
  • You also go to full screen in the View menu.

Preparation

  • Print this Times Tables Chart.
  • Print this Square Line Paper.
  • Collect a few straws or pencils or other thin sticks.
  • Write the title of this challenge and today's date on a fresh page in your maths journal.

Picture Puzzle

  • In a moment you will start a slide show called a Picture Puzzle.
  • The Picture Puzzle is the activity. Lots of pictures and a few words.
  • Picture Puzzles don't have to be 'finished' in one lesson.
    They can be revisited and continued at another time.
  • Use the arrows on your keyboard to change slides.
  • Do everything each slide asks before you move to the next one.
  • Go backwards in the slides any time if you want to.
Have fun exploring Rows, Rectangles and Multiplication.

Here's A Plan

There's plenty to learn from this Picture Puzzle. Keep on coming back.
The slide show has three (3) main sections.
Try one (1) section at a time. Each section might be more than one visit.
  • Section 1: Rows
    STOP HERE BEFORE THE NEXT SECTION!
    Rows help you learn your Times Tables.
    • Print this Times Tables Learner as two separate pages.
    • Write your name in the space at the top.
    • You are going to keep this page until you know all your Times Tables.
    • It starts with the ones you already know.
    • Follow the instructions. Page 2 helps you find the answers and has some extra challenges for fun.
    • Come back to the Picture Puzzle after you have set up your Times Table Learner and tried it out.

  • Section 2: Rectangles
    STOP HERE BEFORE THE NEXT SECTION!
    Try some for yourself in your journal.
    • Choose a multiplication rectangle of your own. Use 2 digit x 2 digit numbers.
    • Write it in your journal, then use graph paper to help you work it out.
    • Choose a multiplication rectangle that is too big for the graph paper, for example: 36 x 43
    • Try to work it out. You can't use the graph paper because it's too big. But a sketch might help you.
    • Check your answer another way.
    • When you have tried, come back to the Picture Puzzle. The next section will help you learn how to do the bigger ones.

  • Section 3: Multiplication
    STOP HERE AFTER THE LAST SLIDE!
    When you get this far, every step has been a success and you have done very, very well. Even if it took you days, or weeks, or months.
    It took mathematicians centuries to learn how to do multiplication like we do it!
    • It's up to you to keep using your TIMES TABLE LEARNER so you can answer in a flash.
    • Keep on practising multiplications. What's the biggest one you can do?
    • Start a new page in your journal called My Multiplication Page.
      • Write a multiplication challenge you think might be hard for you.
      • Perhaps 3 digit number x 3 digit number.
      • Try to do your own challenge.
      • Check your answer another way.
      • Come back in a few days and challenge yourself again.

Just Before You Finish

For this part you need your maths journal and your Working Like A Mathematician page.
  • Look at your notes for this activity. Think back through what you did.
  • Draw an oval in your journal.
    • Change it into a face that shows how you feel about multiplication.
    • Add a speech bubble if you wish.
  • How did you work like a mathematician in this activity? Record all the ways.
  • What do you know now that you didn't know when you started Rows, Rectangles and Multiplication?

 

Answers & Discussion

The Picture Puzzle has three sections. If learners have difficulty with a section perhaps they aren't ready for it. Consider using other activities first such as Making and Breaking Rectangles and Exploring Times Tables.

All the answers in the slide show can be checked with a calculator (and in many other ways).

Send any comments or photos about this activity and we can start a gallery here.
