- Demonstrate how to use the Number line modelStrategy. Show your students that they can practise 4 x 3 by jumping on the number line 4 steps at a time for three jumps.

Guided practise(10 minutes)
- Give each student a different multiplication problem on an index card.
- Instruct your students to solve the problem on a blank sheet of paper using a strategy discussed previously.
- Have your students raise their papers up when they are finished.
- As a group, work out three of the students' problems.
Independent working time(10 minutes)
- Divide your students into pairs.
- Hand each pair of students a set of cups with multiplication problems written on them.
- Challenge your students to answer as many questions as possible.
- Direct your students to stack the cups if they get the answer right. Remind them to be honest when they are self-checking.
- Ask your students to test each other using the strategies reviewed earlier.
- Enrichment:Make cups without the answers on the inside, and have your students play the game with these. Make a puzzle with the answers to multiplication questions.
- Support:Use manipulatives with your students so that they can visually see how multiplication involves grouping.
- Give your students clipboards and paper.
- Set up four different stations around the classroom with a multiplication question at each station.
- Instruct your students to number their papers from one to four. Have them write the answers to the questions at the stations corresponding to the number.
- Give your students 2 minutes at each station.
- At the end, collect their papers and evaluate their multiplication skills.
