Grade 3 Arrays and Multiplication PowerPoint

About This Resource

An 11-slide PowerPoint that introduces arrays, rows and columns, and multiplication sentences for a Grade 3 Math class. It moves from the basic vocabulary through worked examples and guided practice to a review, using clear dot and object arrays throughout so students can see the concept, not just read about it.

Overview

This presentation is designed to run alongside the Multiplication Facts and Arrays Lesson Plan's Presentation and Guided Practice sections. It opens by defining what an array is, then builds up the vocabulary — row, column, factor, product — one idea at a time before connecting arrays to repeated addition and finally to the multiplication sentence itself. A teacher-modelling dialogue slide shows the kind of questioning a teacher can use with students, and a guided practice slide gives two arrays for students to build and solve together before an independent-style review slide closes out the deck.

Grade 3 45-55 Minutes Arrays and Multiplication

Lesson Sequence

Display the presentation on a screen or interactive whiteboard as you teach. Use the Learning Objectives slide to set expectations at the start of the lesson, then move through the vocabulary and worked-example slides at a pace that matches your class, pausing to ask questions rather than reading through quickly. The Teacher Model slide is written as a script — read it aloud with the class, or invite a confident student to play the "student" role. Use the Guided Practice slide as a checkpoint before moving students to independent work, and the closing Review slide to check understanding informally before wrapping up.

Classroom Activities

After the Guided Practice slide, have students work in pairs with counters to build the same two arrays shown on screen, then challenge them to build a third array of their own choosing and share the multiplication sentence with a neighbouring pair.

Teacher Tips

When you get to the "Multiplication Is Repeated Addition" slide, resist moving on too quickly — this is the slide that does the most work in connecting a concept students may already sense intuitively (equal groups) to the more abstract idea of multiplication. A slower pace here often pays off for the rest of the topic.

Learning Objectives

Students will be able to describe an array using rows and columns.
Students will be able to write a multiplication sentence to match an array.
Students will be able to explain multiplication as repeated addition of equal groups.

Differentiation

SUPPORT: Pause on the "Reading an Array" and "Rows and Columns" slides for longer, and have students point to and count the rows and columns themselves as you display the array, rather than only watching.
ON-LEVEL: Follow the presentation at its designed pace, participating fully in the Teacher Model and Guided Practice slides.
CHALLENGE: During the Guided Practice slide, ask early finishers to also write the multiplication sentence in the reverse order (for example, both 3 × 4 and 4 × 3) and explain why both give the same product.

Assessment

Use the Guided Practice and Review slides as informal checks — ask students to respond chorally or on mini whiteboards with the multiplication sentence for each array shown. For a more formal check, follow this presentation with the Multiplication Facts and Arrays Quiz.
