# Term 4 - October 8th (F-2)

##### Week beginning October 8th – Foundation to Year 2

Making Longer, Making Shorter

First, Ahmed used interlocking cubes to make a rod four cubes long: • How many cubes did he need to make a rod twice the length of that one?
• How many cubes did he need to make one three times the length?
• How many cubes did he need to make one four times the length?
• How many cubes did he need to make a rod half the length of his first one?
• How many cubes did he need to make a rod a quarter of the length of his first one?

These rods are the ones Ahmed made: • Which one is twice the length of Ahmed’s first rod?
• Which one is three times the length?
• Which one is four times the length?
• Which one is half the length of his first rod?
• Which one is a quarter of the length of his first rod?
• Which one is the same length as his first rod?

#### Solution

• How many cubes did he need to make a rod twice the length of that one? 4×2=8
• How many cubes did he need to make one three times the length? 4×3=12
• How many cubes did he need to make one four times the length? 4×4=16
• How many cubes did he need to make a rod half the length of his first one? 4÷2=2
• How many cubes did he need to make a rod a quarter of the length of his first one? 4÷4=1
• The first picture of blocks is equal to Ahmed’s
• The second is half of Ahmed’s blocks
• The third is a quarter
• The fourth is twice Ahmed’s blocks
• The fifth is three times Ahmed’s blocks
• The last one is four times Ahmed’s blocks
