The task is designed to show that random samples produce distributions of sample means that center at the population mean, and that the variation in the sample means will decrease noticeably as the sample size increases. Random sampling (like mixing names in a hat and drawing out a sample) is not a new idea to most students, although the terminology is likely to be new.

This is a modification of the Illustrative Math lesson, Fact Families, https://www.illustrativemathematics.org/content-standards/tasks/1214. This lesson was used with a tier 3 fourth grade intervention math group to help students understand inverse relationships with addition and subtraction. I modified it to meet the students' needs by using just page four of the Triangle Worksheet attached resource from the Fact Families Illustrative Math lesson. I used only this page because I wanted students to understand the 8 related equations of fact families. I also modified this lesson by using fact families of 20 instead of 10 and students used a 20 bead Rekenrek to model the equations. A common misconception my students had was with the subtraction equations; they often would subtract the minuend from subtrahend instead of vice versa.

This is a modification of the Helping With Math lesson, Addition with "Cuisenaire Sandwiches", https://www.helpingwithmath.com/printables/worksheets/addition-subtraction/1oa6-addition-subtraction07.htm. This lesson was used with a tier 3 fourth grade intervention math group to help students understand the inverse relationship between addition and subtraction. I modified it to meet the students' needs by having students find partners of numbers up to 20 and had them write the related subtraction equations instead of just the addition equations. Students also modeled the subtraction with the Cuisenaire Rods.

The rules of Krypto are amazingly simpleäóîcombine five numbers using the standard arithmetic operations to create a target number. Finding a solution to one of the more than 3 million possible combinations can be quite a challenge, but learners love it. This game helps to develop number sense, computational skill, and an understanding of the order of operations. Play this game online or use a deck of Krypto cards.

This lesson plan provides the teacher with an activity for introducing the game Krypto, which helps to develop number sense, computational skill, and an understanding of the order of operations. Players are given five number cards. They combine them, using the standard arithmetic operations, to create a target number. As students investigate the game, they develop strategies for finding solutions efficiently. The plan includes learning objectives, materials needed, questions to ask students, assessment options, extensions, teacher self-reflection questions, and a link to the online version, Primary Krypto, (catalogued separately).
