Florida B.E.S.T. MA.1.NSO.1

MA.1.NSO.1 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.1.NSO.1.1

  Starting at a given number, count forward and backwards within 120 by ones. Skip count by 2s to 20 and by 5s to 100.

• MA.1.NSO.1.2

  Read numbers from 0 to 100 written in standard form, expanded form and word form. Write numbers from 0 to 100 using standard form and expanded form.

• MA.1.NSO.1.3

  Compose and decompose two-digit numbers in multiple ways using tens and ones. Demonstrate each composition or decomposition with objects, drawings and expressio...

• MA.1.NSO.1.4

  Plot, order and compare whole numbers up to 100.

01

What Students Need to Do

Students continue a count from any given number, including when the tens digit changes. They build, draw, read, and write two-digit numbers as groups of tens and leftover ones.

02

What Mastery Looks Like

Given 47, a student can show four tens and seven ones, then explain that 4 means 40. The student can continue 38, 39, 40, 41 without restarting at 1.

03

Common Misconceptions

Students may treat both digits as separate counts, saying 47 is 4 and 7 instead of 40 and 7. They may reverse digits or count 38, 39, 40, 50.

04

How to Assess It

Exit ticket: Write the next four numbers after 58. Then draw tens and ones to show 63, and label each digit’s value.

1. 01

   Give students straws to bundle into tens, then call out two-digit numbers for them to build with bundles and single straws.

2. 02

   Ask, “In 52, what does each digit tell us?” Have students explain with words, drawings, or equations.

3. 03

   Play a counting circle starting at 27, with students taking turns saying the next number and earning a point at each new ten.

4. 04

   Use a classroom supply order, such as 34 pencils, and have students show how many packs of ten and single pencils are needed.

• MA.2.NSO.1

  Understand the place value of three-digit numbers.

• MA.4.NSO.1

  Understand place value for multi-digit numbers.

• MA.5.NSO.1

  Understand the place value of multi-digit numbers with decimals to the thousandths place.

• MA.3.NSO.1
