Students skip-count by 5s within 1000, starting from various numbers. They identify patterns on a number chart and use skip-counting to solve problems.

2.NBT.A.2: Count within 1000; skip-count by 5s, 10s, and 100s.

Students skip-count by 10s within 1000 and notice how the tens digit changes. They practice counting forward and backward by 10s from any starting number.

2.NBT.A.2: Count within 1000; skip-count by 5s, 10s, and 100s.

Students skip-count by 100s within 1000 and observe how the hundreds digit changes. They connect skip-counting by 100s to adding and subtracting hundreds.

2.NBT.A.2: Count within 1000; skip-count by 5s, 10s, and 100s.

Students read and write three-digit numbers using base-ten numerals. They match numerals to base-ten block representations.

2.NBT.A.3: Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.

Students read and write three-digit numbers using number names. They practice translating between word form and standard form.

2.NBT.A.3: Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.

Students represent three-digit numbers in expanded form by breaking them into hundreds, tens, and ones. They convert between standard form, word form, and expanded form.
