10X Bigger!
Rating

Students will explore multi-digit numbers and the relationship between ones, tens and hundreds; a digit in one place is 10x the digit in the place to its right. Students will use their bodies to represent digits in multi-digit numbers up to the hundredths place and compare these numbers using <, =, >. Students will use their bodies as multi-digit numbers to add and subtract.

A-CED Regular Tessellations of the plane
Rating

This task examines the ways in which the plane can be covered by regular polygons in a very strict arrangement called a regular tessellation. These tessellations are studied here using algebra, which enters the picture via the formula for the measure of the interior angles of a regular polygon (which should therefore be introduced or reviewed before beginning the task). The goal of the task is to use algebra in order to understand which tessellations of the plane with regular polygons are possible.

Algebraic Equations, Inequalities, and Properties

This lesson is about trying to get students to make connections between ideas about equations, inequalities, and expressions. The lesson is designed to give students opportunities to use mathematical vocabulary for a purpose to describe, discuss, and work with these symbol strings.The idea is for students to start gathering global information by looking at the whole number string rather than thinking only about individual procedures or steps. Hopefully students will begin to see the symbol strings as mathematical objects with their own unique set of attributes. (7th Grade Math)

Angle Hunting
Rating

In this activity, learners use a hand-made protractor to measure angles they find in playground equipment. Learners will observe that angle measurements do not change with distance, because they are distance invariant, or constant. Note: The "Pocket Protractor" activity should be done ahead as a separate activity (see related resource), but a standard protractor can be used as a substitute.

In this problem students are comparing a very small quantity with a very large quantity using the metric system. The metric system is especially convenient when comparing measurements using scientific notations since different units within the system are related by powers of ten.

Arabic 4 us is a site dedicated to children's material. It features a number of lessons on basic words, numbers, and the alphabet. Additionally, the site features content on the Qur'an, brief prayers, and religious songs. There is a separate section for parents which allows them to print material categorized by each letter of the alphabet, which would provide words to their children to memorize.

إن البدو في جزيرة العرب وبلاد فارس قديماً قد جعلوا من الشعر شكل فني حواري. فنجد أن العديد من الأشكال الشعرية قد تطورت من رحم الطبيعة التشاركية للشعر القبائلي. واليوم في معظم الثقافات العربية ربما لا تزال ترى سرد للحكايات ومسابقات للشعر العفوي في الشوارع. ويعتبر فن تحويل القافية إلى سجال لفظي ماكر بمثابة علامة على الذكاء ووسام شرف لمن يتقنه. وهنا سيتعلم الطلاب حول بدايات وتركيبة الشعر العربي.

Area and Perimeter
Rating

This lesson is based on the results of a performance task in which we realized that students' understanding of area and perimeter was mostly procedural. Therefore the purpose of this re-engagement lesson was to address student misconceptions and deepen student understanding of area and perimeter. The standards addressed in this lesson involve finding perimeter and area of various shapes, finding the perimeter when given a fixed area, and using a formula in a practical context. Challenges for our students included decoding the language in the problem and proving their thinking. (7th Grade Math)

This task provides a real world context for interpreting and solving exponential equations. There are two solutions provided for part (a). The first solution demonstrates how to deduce the conclusion by thinking in terms of the functions and their rates of change. The second approach illustrates a rigorous algebraic demonstration that the two populations can never be equal.
