Here is an idea from Christy's Clipart.
 

"I really loved the way the Primary General Board members taught this when they came and did a music workshop in our stake. 

Attention Getter: GAK 240 (Jesus Christ) and a mirror. She had a child come up and look at the picture and the mirror and tell the things that were similar (two eyes, hair, smile, red shirt, etc…). Our goal is to be like Jesus and Heavenly Father. She asked if we would actually start to look like Jesus as we followed his example.  Scriptures: 3 Nephi 11:6-8, John 13: 34-35, Alma 5:14

At this point she began teaching the song. She would direct our listening and then sing a line. She would say, "Who am I trying to be like?" and then sing, "I'm trying to be like Jesus." Then she would say, "If you are trying to be like Jesus, too, sing this line with me." "Now listen to what I am doing to be more like Jesus." "I'm following in his ways." "If you are trying to follow in Jesus' ways, too, sing that line with me." Etc… She did this until she got to the line, "But I try to listen as the still small voice whispers," (Her listening prompt for this was, "What is another name for the Holy Ghost?"). She said, "Sing to this point and then listen very carefully and I will whisper what the still small voice says."  Then she had them repeat it in a whisper. She then challenged them to listen to the still small voice during the week and bore her testimony (it only took 30 seconds to bear testimony here) of the Holy Ghost. She said this is as far as she would go on this song in one week. She stressed that we often try to teach too much in one week. Variety: A comparison to a song with a similar message, "Love One Another" (CS 136) Involvement: She had a poster with Christ's picture and a mirror in the middle and pockets around them labeled with letters spelling GENTLE and LOVING. In each pocket there were red and blue cards. Red cards were thought cards and blue cards were deed cards. She had a child come up and draw either a thought or a deed card and read it aloud. She said to be sure to use situations that are familiar to the children or you will loose their attention. For example, you wouldn't use a situation about being cut off by a bad driver with Primary children, you would use a situation about a bully or problems at school, etc… After the child read the situation, before they answered the situation, she had the children sing "Love one another as Jesus loves you…" to the end of the song. Then the child would answer what to do in that situation. After they answered she showed the child the picture of Jesus and had them look into the mirror and praised them that they were becoming more like Jesus because they were making the right choices."  (Idea by Shauna)
 

Help the children choose visual aids for this month’s song, “I’m Trying to Be like Jesus” (pp. 78–79). Choose pictures from the GAK and the Primary 7 manual picture kit that depict scenes from Jesus’ life. Also choose pictures from the Primary 1, 2, and 3 manual picture kits of children involved in acts of kindness or service and of children who are facing moral dilemmas. Hang the pictures around the Primary room, leaving the front wall blank. Teach the song at the beginning of Sharing Time. Instruct the children to listen while you sing the song and to think which of the pictures would help them remember the words. Sing the entire song. Then sing the first phrase, “I’m trying to be like Jesus.” Have a child choose a picture that helps her or him remember that phrase; move it to the front wall. Have everyone sing the first phrase. Repeat for each phrase of the song. Have the children sing the entire song several times.  At the end of Sharing Time, review the song by placing the chosen pictures on the wall in random order. As the Primary sings the song, have a child find the picture for the first phrase and hold it. Select other children to choose and hold the pictures in order as the Primary continues to sing. If you have separate Sharing Times for younger and older children, record the order of the pictures chosen by each group so that the same ones can be used for the song in upcoming weeks.
