This sample lesson was design to introduce TEK 4.2A - Interpret the value of each place-value position as 10 times the position to the right and as one-tenth of the value of the place to its left.
It could also be used to introduce CCSS 4.NBT.1 - Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.
More to come:
This same presentation will be translated in Spanish. I will soon be adding task cards in both languages to complement this lesson.
