Your little math learners have been working on solidifying their number sense by using ten frames, and composing and decomposing numbers. They’ve mastered the 1-10 Base Ten Math Activities Packet and now they are ready to use the skills they’ve learned to tackle two-digit numbers with the next set of fun and colorful base ten blocks math activity slides.

What is Base Ten?

As stated in the first packet, the technical definition for ‘base ten’ is just another name for the decimal number system. Simply stated…base ten is all about representing place value.

It would be beneficial to allow children to work with an actual, physical set of base ten blocks math manipulatives before (or in conjunction with) the activities in this packet.

Moreover, make sure your students know the correct math terminology for the blocks to represent base 10 and can verbally use the vocabulary to describe the expanded form of the number.

Unit: Represents One (the small yellow cube) and is displayed in the Ones Place Value Column on the Number Mat Slide.

Rod: Represents 10 (the long narrow set of 10 blue blocks) and is displayed in the Tens Place Value Column on the Number Mat Slide.

Expanded Form: Showing the value of each number. Example: the expanded form of 13 is 10 + 3. (10 in the tens place and 3 in the ones place)

Numbers 11-20 Activities

This is the second FREE Spring packet in a series of three math activity packets using base ten blocks that are available to download for Google Slides or Seesaw. After downloading the file, make a copy for each child to use.

One stationary rod and one unit base ten block are provided on each number mat slide as a virtual mathematical manipulative. On every slide activity students will click and drag the correct number of blocks to the tens and ones place value column to visually represent the number (11-20) featured on the mat.

Printable Worksheets Extend the Learning

The ‘teen’ numbers are difficult for young students, so being able to print the math activity slides and provide physical manipulatives can help increase children’s understanding.

Use a base ten rod and ten units for children to physically move to the correct place value column. If you don’t have any base ten blocks, you could substitute them with unifix cubes or legos.

Another activity perfect for individual students or for a small group math center activity is to use the printed worksheets as task cards. Slide the worksheets into a sleeve protector and have children use dry-erase markers to draw rods and units to represent the number on the mat.
