You need to find things that are longer or shorter than the foot. Can you draw some of them in your book, or take some photographs.
Now can you measure the foot with different objects e.g. stones, cubes. Does the answer change when you use different objects? I wonder why that is?
If you would like another activity you could measure the beanstalks. Print off these beanstalks or draw your own.
Here is a challenge:
Can you find the difference between the tallest and shortest beanstalk?
How many more objects does the tallest beanstalk measure?
Could you use a ruler to measure how many centimetres the beanstalks are?
If you have a printer you could print off the beanstalk height measuring chart. How tall are you? Who is the tallest in your house? We would love to see some photographs.
