Numbers to 10,000

How big is a thousand really?

Can you build 1,000 without counting all the way to 1,000?

Watch first

Watch how ones build into tens, hundreds, thousands and beyond.

What you need

Tick each one as you find it — 0 of 5 ready.

Stay safe: Do not put rice or beads in your mouth, ears or nose. Sweep up spills so nobody slips.

Plan the fair test

Objectives this evidences

Recognise the place value of each digit in a four-digit number (thousands, hundreds, tens, and ones)
Count in multiples of 6, 7, 9, 25 and 1000

Do it, one step at a time

Step 1 of 5

Step 1. Count exactly 10 grains into a teaspoon. Look hard at how little that is.
Step 2. Make 10 of those tens in one cup, counting in tens as you go. That cup now holds 100.
Step 3. Fill ten cups the same way. Ten hundreds is one thousand — write the number 1,000 and label which digit is the thousands.
Step 4. Now time yourself: how long did one hundred take? Multiply by 10 to estimate the thousand, then check against the real time.
Step 5. Finally, take 1,000 away from your pile ten times over in hundreds, writing the number each time: 1,000, 900, 800 and on past zero if you can imagine it.

What should happen

Counting in hundreds is roughly ten times faster than counting in tens. Grouping is exactly what place value does for us.

Think about: Your estimate from the timer — was it too high or too low, and why might that be?

Write up your result

What did you measure, and what pattern did you see?

A sentence or two is enough to save it.
