With cross-age learning, mathematics can be lots of fun! For example, little buddies can use and count the number of blocks, popsicle sticks, or other unusual measuring tools to see and record the lengths of big buddies' feet, arms, and other body parts!

Title of Lesson: Geometry Shapes

Grade Range: 2nd+5th
Introduction:
Students make geometry shapes that they have been studying.
Materials needed:
Toothpicks and gumdrops or marshmellows, construction or butcher paper

Methodology:

1. Big buddies review geometry shapes: triangle, rectangle, pentagon, hexagon, octagon, and other shapes that the little buddies will know.
2. Little buddies study shapes in math class.
3. Buddies get many toothpicks and marshmellows. Together, they build flat shapes. (You could also build cube, rectangular prism, etc.)
4. Discuss shapes as a class - quickly.
5. Buddies eat the gumdrops or marshmellows.

Title of Lesson: Measurement, Map Making

Grade Range: 1+4
Introduction:
Students learn to measure the buildings at school. Use unifix cubes to put in sale, trace on paper and cut out buildings, paste on large butcher paper.

Materials needed:
Metric measurement meter sticks, wheel, unifix cubes, butcher paper, paste or glue, scissors, pencils, and markers.

Methodology

1. Students take tour of school and notice buildings.
2. Talk about how to measure, using meter sticks.
3. Buddies measure all buildings at school, distance between building, etc.
4. Report information on paper, using unifix cubes at a scale of 1 cube for 10 meters.
5. On butcher paper, trace out the shape of the building, using the unifix cubes as a pattern.
6. Cut out and paste shapes to large butcher paper, making sure they are appropriately placed.
7. Label names of teachers, room numbers and building. Put in walkways, halls, grass area, etc.

Title of Lesson: Borrowing & Regrouping

Grade Range: 2/5
Materials needed: Pencils, 10s & 1s blocks, worksheet with 10-12 problems (from book or own)

Methodology

Prep

1. 5-minute review of borrowing with 5th graders.
2. Discuss how to teach and what markings mean.

Buddy Time

1. Little buddies practice a borrowing problem, explaining markings and why they do or do not borrow.
2. Big buddies check work.
3. Same for problems 2-12.
4. Early finishers practice + or – facts.
