Intro to math contests1:07
Discover how math contests challenge you with puzzles, number patterns, and detective-style thinking. Join this course to sharpen problem-solving tricks, build confidence, and improve math and contest skills.
How to get ready for math contests?1:20
Practice with bar models to tackle addition, subtraction, multiplication, and division by drawing pictures, solving puzzles, riddles, and exercises; read questions carefully and explore multiple ways of solving, staying positive.
Let’s explore some fun math contest questions1:36
Explore fun math contest questions that boost pattern recognition, probability, and careful reading of word problems, with practice strategies to tackle real contest-style puzzles.

Intro to bar models2:50
Draw bar models, like lego blocks, to visualize problems with houses A, B, and C. Use the total of 11 and known values to find that C has four people.
Bar models for additions2:09
Learn to solve problems with bar models, applying add for totals and subtract for parts, using a chocolate distribution example for grades 3 and 4.
Bar models for subtractions3:00
Apply bar models to subtraction problems with a total and missing part; compute 159 minus 76 to find 83 dollars Tamara must save to buy the shoes.
Bar models for multiplications2:42
Use bar models to solve multiplication problems by visualizing repeated groups; for example, John has 3 games and Sandy has twice as many, total 6.
Bar models for divisions3:03
Explore how bar models solve division problems by using total and equal groups, recognizing clues like how many times as many, and understanding division as the inverse of multiplication.
Intro to comparison bar models2:14
Explore how comparison bar models solve a three-player dice puzzle, showing Anna's score two more than Cena and one less than Boris to identify Cena as the lowest.

Solving a two-step problem (part 1)7:19
Use bar models to solve a two-step puzzle about 24 people in six houses on three roads. Corner houses A, C, and E sum to 10.
Math Quiz for Practice
Multistep- Counting and Division2:53
Apply bar models to a multi-step counting and division problem, showing how two cookies per day lead to five days, with the 10th cookie on Wednesday and start day Saturday.
Division and multiplication for multistep problem5:11
Use power models and bar diagrams to solve a multistep division and multiplication problem with orange and apple bags, uncovering the total weight and which bags hold oranges (1,3,5).
Multistep problem to find starting number after adding more numbers to it4:15
Use bar models to solve a multistep lemonade problem. Determine the initial money by comparing $50 after 5 lemonades and $125 after 20, revealing $25 start and $5 per lemonade.
Subtract common elements for total4:31
Learn to use bar models to solve distribution problems by adding distinct boxes for blue and yellow pins, subtracting the three shared boxes, and finding the remaining empty boxes.

Comparison bar model- multistep problem 22:45
Learn to solve multistep comparison problems using a bar model, compare distances like Arya, B1, and Costco, and use difference markers to find the gap between bars.
Solving a two-step problem (Comparison)3:01
Use comparison bar models to determine the lowest drone height: Ben’s is 3 meters higher than Dean’s; Amy and Ben are equal; Sarah’s is 5 meters under Amy’s.
