A Big Mistake is a picture book by Richelle Lovegrove for Manitoba First Nation Education Resource Centre. With illustrations by Amber Green the book explores friendship, gifts and generosity. When Summer’s best friend compliments the necklace her kokum (grandmother) gave her, she remembers her Elder’s teaching and gives the necklace away. But when her kokum comes over for supper, Summer worries that she made a big mistake by giving away such a special gift. The girl began to worry about giving kokum's special necklace away to her friend. Kokum knew her granddaughter was troubled with worry about something. Kokum learns the cause of the girl's worry and helps Summer reflect on her choice. Understanding the message of sharing may be a difficult concept to put into real life situations and this simple story assists young readers in making choices when it comes to sharing and talking with a parent or Elder about their worries or anxieties. Ideal for primary level discussions.
