Resources to mark the 100th day of school with math activities. Challenge students to generate 100 different ways to represent the number 100. Students will easily generate 99 + 1 and 50 + 50, but encourage them to think out of the box. Challenge them to include examples from all of the NCTM Standards strands: number sense, numerical operations, geometry, measurement, algebra, patterns, data analysis, probability, discrete math, Create a class list to record the best entries. Some teachers write 100 in big bubble numeral style and then record the entries inside the numerals.

A task related to standard 3.MD.7d, additive area of rectilinear figures. Students find the area of the parts of a pool to ultimately find the area of the entire pool.

This task provides students the opportunity to identify a mistake in reasoning related to the relationship between multiplication and division.

4.OA.1. Interpret a multiplication equation as a comparison and represent verbal statements of multiplicative comparisons as multiplication equations.

This resource provides students with the opportunity to solve a multi-step contextual word problem with a degree of difficulty appropriate to Grade 4, requiring application of knowledge and skills.

Students will use objects found in the outdoor classroom to create rectangular arrays and write equations to express the total. \n\nStandard(s): 2.NC.OA.4\nUse addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express

In this task, the students are not asked to find an answer, but are asked to analyze word problems and explain their thinking. In the process, they are faced with varying ways of thinking about multiplication.

In this lesson, students in this lesson will learn about, connect, and apply the use of the area to a real-world problem—creating a planting guide for the garden. Students will determine the square footage of the garden and use this information, along with a planting chart to create their own plan. \r\n\r\nBackground for instructors:\r\nMath in the REAL world: Area and square feet\r\n\r\nSquare foot gardening is one way that ensures a vegetable garden bed can thrive. It is used to ensure not too many plants of a specific variety are planted in a single area. Using the square foot model keeps plants properly spaced, providing a perfect real-world context to teach area, apply multiplication strategies, and have students work collaboratively. Most garden beds are 8 x 4 resulting in 32 square feet to work with. It is possible however to have beds of different sizes. While 32 square feet to work with is what is used in this lesson, the methods and chart can be used for any rectangular planting area.

Remember your multiplication tables? ... me neither. Brush up on your multiplication, division, and factoring skills with this exciting game. No calculators allowed!

Brush up on your multiplication, division, and factoring skills with this interactive multiplication chart. Three levels and timed or untimed options are available.

This activity will help students apply their knowledge about arrays to a real-world situation. Students will design buildings and create an array of windows for eah building. Students will use the array to write an addition sentence and a multiplication equation to determine how many windows each building consist of.

The students will use their knowledge of repeated addition to determine the total number of objects in equal groups.

Every math teacher struggles to find ways to encourage students to master their basic facts. Whether for addition and subtraction facts or for multiplication and division facts, teachers collect many ideas from which they can draw activities to meet the varied needs of learners in their classes. Games and Who Has? activities are especially motivational and continual play can help students develop fact fluency in an effort to master the games and capture the most points.

BPCC Open Campus - Math 097: Basic Mathematics is a review of basic mathematics skills. Here's what's covered: -fundamental numeral operations of addition, subtraction, multiplication division of whole numbers, fractions, and decimals -ratio and proportion -percent -systems of measurement -an introduction to geometry NOTE: Open Campus courses are non-credit reviews and tutorials and cannot be used to satisfy requirements in any curriculum at BPCC.

Students will engage in constructed response contextual tasks involving multiplication and division. Tasks include a variety of problem situations (e.g., unknown product, unknown group size, or unknown number of groups) of increasing complexity. Students will represent their thinking in multiple ways (e.g., pictorially, symbolically, or textually) to demonstrate conceptual understanding.

The Caribbean Examinations Council (CXC) Caribbean Secondary Education Curriculum (CSEC) mathematics syllabus has been used to guide the selection and sequencing of quality Open Education Resources (OER) to create a free textbook or online course. The resources have been collected and vetted by experienced mathematics teachers and organised to allow a 'reader' gain mastery of each of the CSEC topics and objectives.  

In this video segment from Cyberchase, Inez and Lucky figure out how to keep track of the number of clones as they continue to multiply.
