Place Value and Properties of Operations

Big Ideas

Mathematical relationships among numbers can be represented, compared, and communicated.

Mathematical relationships can be represented as expressions, equations and inequalities in mathematical situations.

Numerical quantities, calculations, and measurements can be estimated or analyzed by using appropriate strategies and tools.

Patterns exhibit relationships that can be extended, described, and generalized.

Essential Questions

How can mathematics support effective communication?

How are relationships represented mathematically?

What does it mean to estimate or analyze numerical quantities?

What makes a tool and/or strategy appropriate for a given task?

When is it is appropriate to estimate versus calculate?

How can patterns be used to describe relationships in mathematical situations?

This is a great video, compliments of the Khan Academy, it shows how to round whole numbers to the nearest ten and hundred.

Here is another great video for rounding, compliments of Kids Academy!



The following two videos showcase adding multi-digit numbers with regrouping. I like the way they show different strategies, not only the traditional way!

Click on the cards and you will be sent to a great site that has numerous games to practice addition and subtraction fluency of basic facts with playing cards.

Pyramid

Click on the image to the left and you will be sent to a site titled "Math Geek Mama." She has a fun game called Pyramid. It helps work on addition fluency! Below I attached a few variations of the game:

  • Try working on subtraction

  • Get multiple packs of cards and to the left side of the number already there, add a 1, 2, 3, etc. to make teens, twenties, thirties, etc. This way you can play the same game working with larger numbers.

The Thinking Blocks app, teaches children how to model and solve word problems involving addition and subtraction.

This great App was created by Math Playground and is available through the App store.
