Filling Shadows With More and Less
Lesson 5 of 10
Objective: SWBAT alter their designs to use more or less pattern blocks to cover the same area.
I gather the students in front of the Smart Board. I will use a 10 sided die to practice their complements of 10. I will use the document camera to project the die as it is rolled. The idea is that I will introduce this activity today and then differentiate it in future lessons (differentiate by using 20 sided dice and work on compliments of 20). However, today I am just focused on introducing the routine.
I start by explaining that the game will have us focus on making 10. I will roll a number and say the number, then your job will be to figure out what number is needed to make 10. However, I don't want you to shout it out, but rather put your thumb on your chin once you know the answer.
I have the students each get a clipboard and a pencil and I give them a piece of paper. Following the established Quick Flash routine, I ask the students to look at the shape card that is flashed to them and to draw what they saw.
Once they have made their attempts, I ask them to describe what they saw and how they remembered what to draw. If the correct shape names are not used, make sure to introduce them and model the terminology use.
Repeat this as time allows. The shape cards are in the section resource (Shape Combination Cards).
I will introduce the first two activities because they are new to the class. The third one is linked because it was introduced in a previous lesson.
1. Filling with More or Less: Using the worksheet in the section resource titled Filling With More or Less 1,2, & 3 (in the resource section), the students will use pattern blocks to fill the image with very few (less) blocks and then the same image using many blocks (more) blocks. Using the blocks to cover an image, compose and decompose shapes with in the same image is making relationships with quantities (of shapes) CCSS.Math.Practice.MP2.
2. Exploring with Geo Boards: Students create shapes on the geo boards.
3. How Many Ways?: Click link for explanation.
FOr all three of these activities, the students are being asked to use mathematical tools (pattern blocks, geo boards, dice, templates, and recording sheets) in a strategic way (CCSS.Math.Practice.MP5)
Students use a ten sided die and take part in the warm up activity that was introduced at the beginning of this lesson.
