Lesson 1
Introduction to multiplication
Introduction to multiplication
Key:
Assessment For Learning - (AFL)
Assessment Of Learning - (AOL)
Teacher Questioning - (TQ)
Working Mathematically - (WM)
Literacy Activity - (LIT)
Key ideas:
This introductory lesson is fostered around Stage 2 Syllabus dot points because these are essential that students understand prior to beginning this unit. Hence, this entire lesson will focus on revision of Stage 2 Multiplication & Division 2 concepts because I believe that this is a necessary way to start.
Syllabus dot points:
From Stage 2 Multiplication & Division 2
NOTE: These are only revised in the Introduction activity, as obviously all of these dot points cannot be covered in one lesson, and as they are Stage 2 they should have already been covered. I just think it is important to list them all to ensure that as a teacher you are aware of what the students have already learnt regarding this topic.
From Stage 3 Multiplication & Division 1
Relevant Working Mathematically indicators:
Assumed prior learning:
Learning goals:
By the conclusion of the lesson, students will be able to demonstrate and explain single-digit multiplication, and recall multiplication facts of up to 10x10 WM - Fluency, Reasoning, Communicating
Lesson length: 50 minutes
Resources:
Watch this video about the relevance of multiplication:
TQ: What are some examples of multiplication in the real world that weren't in the video?
WM - Understanding
Outline classroom behavioural expectations and learning goal for the lesson and write on the whiteboard:
WM - Fluency, Communicating
Brainstorm / mind-map
Students will have a mini-whiteboard each and be asked to create a mind-map to brainstorm everything that they remember about "Multiplication"
This activity is to be completed individually and after 3 minutes they will be asked to share their answers with a partner for 2 minutes. There will then be a class discussion AOL about what students have written, to get students brains activated regarding this new unit.
The teacher should write down some of the class' answers on the whiteboard.
TQ: When students answer questions, if it is incorrect or not clear, ensure that you ask them to explain themselves or ask why they suggest that answer?
Below are some beginner videos regarding multiplication that would be useful to show any student who is struggling to grasp or recall the concept of multiplication:
Activity 1: Greatest Product game (20 minutes)
Students will work in pairs and be given 2 dice between the pair. Taking turns, each person will roll both dice and write down both numbers, then multiply the numbers together AFL. Once both people have had a turn, the students must compare each roll and see who had the greatest product. Students are to keep track of points using tally marks. While students are playing the game the teacher should walk around the room to ensure that students understand and check progress, giving modifications to the groups who need it.
Students can use the Array Display activity on the website http://www.ictgames.co.uk/ if they are having trouble with the multiplication, it will show this in a visual array and provide the answer.
There will then be a class discussion about the game and the trends.
WM - Fluency, Understanding
TQ: Which numbers were better to roll in order to win each round? i.e. higher numbers such as 6
Activity 2: Ken Ken game (10 minutes)
Students will work individually to complete Ken Ken puzzles ranging from 4x4 to 9x9 that focus on multiplication but include other operations. Students will use this as a revision tool AFL from their knowledge of up to 9x9, and there should be puzzles of varying difficulty so that students can choose if they want to start at an easier puzzle and work their way up, or if they want to try an expert level puzzle.
Teacher note: If not familiar with Ken Ken puzzles, students must place 1 number in each box e.g. if 4x4 puzzle the numbers range from 1-4, and they must sum to the small number in the box abiding by the given operation. The same number cannot be in the same row or column, i.e. each row and column must have 1, 2, 3 and 4.
WM - Fluency, Understanding, Problem Solving
TQ:
Exit cards AFL
Students will be given exit cards (see below) with some multiplication questions on them, ranging up to 10x10. The questions will vary in difficulty, and the teacher will instruct students to complete as many of the questions as they are able to and hand them in prior to leaving the classroom.
WM - Fluency, Understanding
Conclude lesson by referring back to the learning goal for the lesson and collecting exit cards, as well as informing students of the required homework.
Students are to write down on a blank A4 sheet of paper a 10x10 multiplication quiz comprising of 10 questions and bring it to class anonymously for next lesson.
