Number Sequences Lesson Plan for 1st Grade

A ready-to-teach number sequences lesson for 1st Grade. Everything below is classroom-tested structure: an objective, a 45-minute sequence, a way to check who got it, and 2 printable practice pages.

Approximately 45 minutes

Learning objective

Identify and continue a number sequence by finding the pattern
Fill in missing numbers in a sequence using the rule
Recognize increasing and decreasing number patterns in a row

Materials

Counting in sequence (1-50) - Super Star
Counting in sequence (51-100) - Star Rainbow
Pencils, and whiteboard space for the modeled examples

Lesson steps

1. Warm up together (5 min)
Open with a quick count-around or number talk that touches number sequences. Ask students where they have seen number sequences outside of math class. You are listening for who already has the vocabulary and who does not, so keep it light and let several students answer.
2. Model it (I do) (10 min)
Work two examples of number sequences on the board, thinking out loud the whole way. Say the quiet parts: what you notice first, which step you do next, and why. Deliberately make one small error on the second example and let the class catch it.
3. Practice together (we do) (10 min)
Work three more problems as a class. Ask a different student to supply each step rather than the whole answer. If a step stalls, drop back to concrete objects or a drawing before moving on.
4. Independent practice (you do) (15 min)
Hand out "Counting in sequence (1-50) - Super Star". Students work independently while you circulate. Note who is fluent, who is counting on fingers, and who has not started, because that grouping drives tomorrow's small group.
5. Close the loop (5 min)
Pull the class back. Ask one student to explain a problem they got right and one to name something that is still confusing. End on the confusion, not the success, so students learn that naming a gap is normal.

Check for understanding

Collect the practice pages and sort them into three piles: fluent, developing, and not yet. Any student in the third pile needs number sequences retaught in a small group before the class moves on.

Differentiation

Extra support. Students who stall: pull them into a small group and rebuild number sequences with concrete materials or a simpler text before asking for the written work again. Do not send the page home as homework, it will just rehearse the misunderstanding.

Extension. Students who finish early: ask them to write their own number sequences problem for a partner to solve, then check the partner's work. Creating a problem is harder than solving one and it surfaces whether they really understand number sequences.

Questions teachers ask about teaching number sequences

What number sequence skills should first graders develop?

First graders should count forward and backward from any number within 120 (CCSS 1.NBT.A.1) and skip count by 2s, 5s, and 10s (building toward 2.NBT.A.2). They should identify missing numbers in a sequence and understand that each number is one more (or one less) than the number before (after) it.

How do you teach number sequences to first graders?

Hundred charts are essential visual tools for number sequencing. Use a pointer to count together, skip over numbers in skip-count patterns, and ask students to find missing numbers by finding their position on the chart. Worksheets with partially completed number lines and sequence fill-in-the-blanks build sequential counting fluency.

What is skip counting and why does it matter in first grade?

Skip counting means counting by a number other than 1 - by 2s, 5s, or 10s. It is a foundational skill for multiplication and understanding multiples. First graders who skip count fluently by 5s and 10s develop much stronger sense of how our number system is organized. Skip counting by 2s builds awareness of even numbers and later supports multiplication facts.
