Digit Place Value in Millions

Digit Place Value in Millions: a free Grade 5 math game for ages 10-11. Kids find the digit in a given place of a 7-digit number. Each round draws 10 questions; instructions are read aloud and every answer is checked.

How it plays and why it helps

A seven-digit number looks harder than it is. Digit Place Value in Millions shows Grade 5 students that the commas do most of the work. Each round has ten questions such as "In the number 8,053,972, which digit is in the hundred thousands place?" Your child chooses from four digits. Every answer is checked, and the explanation lists each digit beside its place name, from millions down to ones.

This is place value in groups of three. The comma sets off the thousands group, the next one sets off the millions, and inside each group the pattern repeats: hundreds, tens, ones. Once your child sees that pattern, the long names stop being scary. The hints point the same way: find the right group first.

The common error is counting places from the left end. Your child may pick 8 for the hundred thousands in 8,053,972, when the answer is 0. Ask, "Which group are we in?" Zeros trip children up too. Close on the process: "You found the group first, then the place."
