This resource accompanies our Rethink 2nd Grade Math Number & Operations in Base Ten unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning. 

Students create their own Mystery Numbers by giving clues about the name, value, and multiples of the digits which comprise the number.

Base Ten BINGO is a fun educational learning activity for children to practice counting by one's, ten's, hundred's and thousand's. First children select the desired place value and grid size. Next, add up the blocks on the right and click the corresponding number on the left. Learn place value while playing BINGO!

This interactive/virtual manipulative provides base ten blocks that consist of individual "cubes," "rods," "flats," and "thousands-cube" (ten of each set for base 10). The activity reinforces students' knowledge of thousands, hundreds, tens, and ones. Students can either enter a number and see the visual representation, or they can create a number by selecting the appropriate base ten blocks. As students add or remove base 10 blocks, they can see the numbers increase or decrease to determine if they are on the right track.

Use the base ten blocks to create a model of the 3- digit numbers.

In this assessment task, students use three given digits to make the biggest number they can.

In this assessment task, students show their understanding of place value and explain their thinking.

This short video and interactive assessment activity is designed to teach third graders about translating number patterns into words.

This short video and interactive assessment activity is designed to teach second graders about turning words into numbers using a place value diagram.

This short video and interactive assessment activity is designed to teach second graders about writing prices of items.

Create a picture using base ten blocks.  Write the total place value of the blocks in your picture.
