Number Lines

Here are some number line story problems that include "secret jumps".

making sticks

Encourage students to explore how to connect interlocking cubes in lines that are equal but made of varying multiples.

Four Go

This challenge is a game for two players.  Each player chooses two numbers from a grid and chooses to either multiply or divide (try adapting for addition and subtraction) them and represent the action on a number line.  The trick is for the math to fit on the number line without "falling off".  If the math "falls off", the player misses a turn.

The world of tan

This is a series of Narrative logic challenges related to Tangrams.  Appropriate for ages 5-11

Method in multiplying madness?

This site provides 8 videos showing 4 different methods for working out multiplication of larger numbers.  Each student in a small group can take one method to learn, practice and teach the other group members.  There are great discussion questions included to encourage students to think more deeply about why the methods work.

Factor Lines

Play an online number game where you need to arrange numbers using it's multiples and factors.

Fractional triangles

Use the lines on this figure to show how the square can be divided into 2 halves, 3 thirds, 6 sixths and 9 ninths.

blockout

Players in this online Polypad game take turns rolling two dice and creating a rectangle on the game board.  Students type in the multiplication equation onto their array.  The student who finishes filling in the game board wins.

What's in the Box?

What multiplication might have happened to four whole numbers put into the first box in order to end up with the four numbers falling out later?  This is a great extension for students working with arrays and number line puzzles.

Compare the Calculations

Have students analyze various multiplication problems ordering them from easiest to hardest.  This opens up great discussions regarding why one problem might be considered easier than another even though it contains larger numbers.

Fractions

Ferry Sequences: A man named John Farey investigated sequences of fractions in order of size- they are called Farey Sequences.  This activity explores the patterns within these sequences.

Countdown fractions

This is a more challenging version of the common game, Countdown.  The challenge is to use the numbers and factions available, and the four standard operations (addition, subtraction, multiplication and division to hit a target.

Matching fractions, decimals & percentages

This is a basic memory game where you are matching fractions to their decimal and/or percentage counterpart.
