Activity Description
Introducing an exciting digital escape activity focused on Highest Common Factor (HCF), designed to captivate students' interest while reinforcing essential math skills. In this interactive adventure, students embark on a journey to unlock the secret code by solving HCF puzzles presented in a row-by-row format. Students will
- Find HCF of the first 3 blocks of numbers
- If the answers are correct, the next set of numbers will show up
- Students will repeat this for 3 more rows
- When the HCF of all the blocks in the last row is answers, a secret code will show up.
With its immersive and interactive nature, this HCF digital escape activity offers a dynamic and hands-on approach to learning, making math fun and memorable for students of all levels.

Common Core: MATH
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. *For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)*
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. *For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2*.
Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor. *For example, express 36 + 8 as 4 (9 + 2).*.
Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.
