Times Tables Applications

Overview

In this 30-minute lesson (lesson 9 of 10), you will apply known times tables to solve short, real-life word problems. You will choose the correct multiplication facts, record working clearly, and check your answers make sense.

Learning intentions

WALT: Apply multiplication facts in real-life scenarios.

Success criteria

• I can solve at least 3 word problems using times tables correctly.
• I can write a number sentence that matches the story.
• I can explain my method using correct multiplication facts (e.g. “4 groups of 6 is 24”).

Curriculum links

• Mathematics: Number and Algebra — using multiplication facts to solve applied problems involving whole numbers, and communicating solutions with working.
• Mathematics: Problem-solving and reasoning — selecting the correct operation(s), representing the situation mathematically, and interpreting results in context.
• Mathematics: Modelling — using a simple mathematical model (groups/arrays, equal groups, repeated addition) to represent word problems.

Lesson structure (30 minutes)

1. 0–3 min · Warm-up check (recall). Teacher says: “Tell me the answer to: 6×7, 8×5, 4×9.” Then asks which ones you found easiest and why. Student responds with answers and a quick justification (e.g. “I used 6×7 because it’s equal groups of 7, six times.”).

2. 3–8 min · Model a word problem (teacher-led). Teacher models one example on paper: “A snack box has 6 biscuits. How many biscuits in 5 snack boxes?” Prompts: “What does the story tell us—groups or addition? What multiplication fact fits?” Student identifies “5 groups of 6” and writes: 5×6=30, then states “There are 30 biscuits.”

3. 8–10 min · Strategy reminder (how we model). Teacher gives a short checklist on the page:

• Find the “groups” number and the “each group” number.
• Write a multiplication sentence.
• Solve using known times tables.
• Check: does the answer match the story? Student repeats the checklist aloud and marks it “My steps”.

4. 10–20 min · Independent word problems (3 to 4 tasks). Teacher says the student will attempt 3 word problems first, and may do a 4th if time allows. Student solves, showing working and writing a number sentence for each.

Word problem set (choose 3 for core, 4th as time-filler):

• Problem A: “A movie ticket costs $12. What is the total cost for 4 tickets?”
• Problem B: “You fold 8 paper cranes each time. How many cranes after 6 folding sessions?”
• Problem C: “A class has 7 rows. Each row has 5 students. How many students in the class?”
• Problem D (if ready): “A packet has 9 stickers. How many stickers in 3 packets?”

Teacher circulates by monitoring the work (for home teaching, teacher checks each step immediately after the student writes each number sentence).

5. 20–26 min · Error-check and reasoning (show-check). Teacher selects one of the student’s answers (preferably one that is incorrect or uncertain) and asks targeted questions:

• “Which times table did you use?”
• “Is your ‘groups’ number and ‘each group’ number correct?”
• “Does your answer match the context (units)? ” Student revises the solution if needed and writes a corrected number sentence.

6. 26–30 min · Exit ticket (quick proof). Teacher gives one final mini word problem: “There are 6 books per shelf. How many books on 7 shelves?” Student answers with number sentence and final total.

Resources

• Notebook or printed worksheet titled “Times Tables in Word Problems”
• Pencil/eraser
• Timed flashcard set (optional) for 1–2 minutes of recall
• Calculator permission: only if your unit rules require it; otherwise no calculator for multiplication
• Coloured pens or highlighter for underlining “groups” and “each group”
• Answer-check space on the worksheet (units like biscuits, tickets, students)

Assessment

• Formative: observe warm-up recall accuracy and whether the student can explain which times table they used.
• Formative: during independent problems, check that each solution includes a multiplication sentence matching the story (not just a final number).
• Exit ticket: confirm correct use of multiplication facts and correct interpretation of context.

Differentiation

• Support: provide a sentence starter on the worksheet: “This is ___ groups of ___, so we calculate ×.”
• Support: offer an easy first problem that uses a familiar table (e.g. 5s or 10s) before moving to less familiar facts.
• Challenge: if the student finishes early, ask them to solve Problem D and then estimate quickly before calculating (e.g. “3 packets of 9 should be just under 30.”).
• EAL/SEN-friendly: reduce reading load by highlighting key words (each, per, groups, rows, shelves) and allowing the student to circle them.

Success criteria recap for this lesson

• Can solve at least 3 word problems using times tables correctly.
• Writes a multiplication sentence that matches the story for each problem.
• Can check that the answer fits the context (units and reasonableness).
