Kindergarten base ten blocks

Teen numbers as 10 and some more on ten frames, and comparing tens and ones.

Tens and ones with base ten blocks: count, draw, match, compare, cut and paste (with a no-cut number bank), and count blocks to 120.

2nd grade base ten blocks

Hundreds, tens and ones with flats, rods and cubes, digits in each place, and a 100th day page.

About these base ten blocks worksheets

Base ten blocks show place value you can see: a small cube is 1, a rod is 10 cubes, and a flat is 100 cubes. A child can count 34 as 3 rods and 4 cubes.

Kindergarten starts with teen numbers as 10 and some more. 1st grade works with tens and ones up to 120, and 2nd grade adds hundreds.

The sheets are grouped by grade, and the practice sheets have answer keys.

Standards

  • CCSS.MATH.CONTENT.K.NBT.A.1Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
  • CCSS.MATH.CONTENT.1.NBT.B.2Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
  • CCSS.MATH.CONTENT.2.NBT.A.1Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:

How to use them

  1. Use real blocks (or paper ones) next to the worksheet.
  2. Count the rods by 10s first, then count on the cubes by 1s.
  3. Trade 10 cubes for a rod, and 10 rods for a flat, out loud.
  4. Ask children to show a number two ways, such as 3 tens 4 ones and 2 tens 14 ones.

Teaching tips

  • A teen number is always one ten and some ones: 16 is 10 and 6.
  • Zero in a place means no blocks of that size: 405 has no rods.
  • Draw rods as tall lines and cubes as small squares to save time.
  • Read a number from the biggest place to the smallest.

Questions teachers and parents ask

What are base ten blocks?

Base ten blocks are cubes (ones), rods (tens) and flats (hundreds). Ten cubes make a rod and ten rods make a flat, so the blocks match how our numbers are written.

What are teen numbers?

Teen numbers are 11 to 19. Each is one ten and some ones, so 13 is 10 and 3. Kindergarten children learn to see them that way.
