Solve one sided linear inequalities in 1 variable and find max/min integer solution or a list of integer solutions from a set.

• ### Putting whole numbers in order up to 100

Decide which of two numbers from 1 to 100 is the larger. From a list of integers up to 100, arrange in ascending or descending order.

• ### Recognise place value

Read, write and order whole numbers, recognising that the position of a digit gives its value and understand the place value of each digit up to 1000.

## What teachers say about Mangahigh

We’re loved by both teachers and students globally. Here’s the proof!

• Mangahigh turns our students into “maths addicts“ who compete with each other for top scores and gold medals. And since the quizzes reward both accurate recall of knowledge and deep conceptual understanding, every hour they spent having fun makes them better mathematicians. Five stars.

###### Tom Ding

• I have used Mangahigh in my classroom for over 5 years. What keeps me coming back are the math games and wide range of concepts that are offered. But the best part is the fact that the kids LOVE to play it. I have students beg me to assign them Teacher Challenges! Begging for more math work? I am ok with that!!

###### Renee Hernandez

Green Elementary School, Allen, Texas

• Kids loved it; an ADHD student who has NEVER before been able to focus in the last periods of the day; he wouldn't stop till he got a medal! Absolutely phenomenal! His mother is overjoyed, and the rest of the maths staff room were gobsmacked!
