Lesson 2: Adding 1s and 10s

Understanding place value when adding tens

Want to join the conversation?

• How would you draw 100 or 1000 cubes?
• You define another symbol for 10, 100, 1000 cubes or any other grouping that can be multiplied by a manageable amount. Otherwise, with a lot of patience and perseverence :)
• How is it important to put the biggest number on top?
• I guess this depends on the scenario (not defined) and if you are better at addition vs. subtraction (in an equation requiring one of those functions. Maybe not so much the biggest number vs. testing the position and the mechanics you use to get there and comparing it to a different method to see what worked quicker. Then again, you could do something that you are weak at to gain strength as well.

If you want a better answer without the 'coaching', define a specific scenario where you saw this to help someone answer it in context.
