Grade 1 Place value: Free Course

About this course

Place value explains why a digit's position changes its meaning. This Grade 1 course introduces tens and ones, number grids, missing numbers and comparison symbols. Study the complete public source playlist from Khan Academy in English, with all 6 recordings in the on-site classroom. Original lesson titles, source order and repeated entries are preserved.

Course Overview

Worked examples with 25 and 42 connect written two-digit numbers with groups of ten and leftover ones. Number-grid lessons make the counting pattern visible across rows and columns, while missing-number practice checks whether learners can locate a value in the sequence. Greater-than and less-than symbols provide a concise way to record comparisons. The playlist is a short place-value unit, not a complete Grade 1 mathematics programme. Use physical or drawn groups to make the value of each digit visible, and ask learners to explain a comparison using quantities rather than only remembering the direction of a symbol.

How to study the course

• Videos 1–1: this part of the source list includes “Place value example with 42” through “Place value example with 42”. State the quantities and conditions before calculating. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 2–3: this part of the source list includes “Missing numbers between 0 and 120” through “Number grid”. Keep equivalent expressions or representations connected. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 4–4: this part of the source list includes “Place value example with 25” through “Place value example with 25”. Check each operation with a small example before extending it. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.
• Videos 5–6: this part of the source list includes “Greater than and less than symbols” through “Introduction to place value”. Explain a result in words as well as symbols. Keep a brief working note, revisit an unclear explanation and test one example before moving to another part of the material.

Who is this for?

This course suits students, returning learners and anyone strengthening the specific mathematics named in the course. It also provides a recorded reference for revisiting a topic after an earlier lesson or study attempt. Choose examples appropriate to your background and allow time to work through the method instead of judging understanding only by how familiar the terminology sounds.

Before you start

Comfort with the preceding arithmetic or algebra skills is useful. Keep paper, a pencil and a calculator when a lesson uses one. Grade-specific courses assume the learner’s earlier grade-level knowledge.

Put the lessons into practice

Make two two-digit numbers with bundles of ten and loose counters. Write each numeral and explain what its digits represent. Compare the quantities and record the correct symbol. Locate the numbers on a grid and describe what happens when moving one step or one row in the displayed pattern.

This optional study activity is provided by WikiFree for independent practice. Keep your working notes and use the relevant classroom recording to check a step, definition or interpretation. It is not an instructor-marked assignment.

Certificate / Assessment

Watching the public videos and using WikiFree completion tracking does not award a certificate, academic credit, an examination voucher or instructor assessment. Use your practice output to review what you can explain and repeat independently. The recorded lessons provide study material; completion tracking records your progress through that material.
