Do you have a fourth grader learning place value to one million?

Here’s a quick idea on how to make it more fun. Create a color coded place value mat. Then use uno cards that match each color to teach the place value.

Start by teaching just the ones. Refresh on saying the random numbers you lay down. Then add the thousands. Once they have mastered the thousands, add the millions. Repeat until the skill is mastered.

You can then add in teaching about the commas and how they go between each set of three numbers.

If your child is struggling to understand place value concepts, using Legos to refresh on the “ones period” can be helpful. It is also helpful to use Lego’s as manipulatives for showing how each model is 10 times more than the prior one, so each place value is 10 times more than the prior one.

In this video, the teacher describes the value of a digit by writing the number in a place-value chart.

Our number system is called Base 10. 10 unit cubes are equal to 1 long of 10. 10 longs are equal to one flat of a hundred. 10 flats are equal to one large cube of 1000. Each place value can only hold one digit. Each model of our base ten blocks is ten times more than the model to its right.

You put a comma between each group of three digits starting from the right side. You can also use a place-value chart to compare values. You find or compare the value of an underlined digit. The digit 0 has no value. You use it as a placeholder to show an empty place-value.

The teacher talks about how each place-value to the left is 10 times more than the place-value to to the right. She teaches how to see what number you would get if you exchanged two of its digits. You see what would happen if you exchanged two digits in a number and one of those digits was a zero
