Year 2 Maths Problems

Have your students been working on understanding how to use place value skills to mentally add and subtract 10 or 100 from a number? If you are looking for a fun way to have your students review this skill, look no further! Teach Starter has created a set of peg cards for your students to use when learning how to mentally add and subtract 10 or 100 from a number.

Prior to use, the 24 cards should be cut apart. Clothes pegs can be provided if used as peg cards. Students will read the phrase on the card, and determine which of the 3 choices is correct. Then, they can clip a clothes peg to that number, circle their choice or simply record their choice on the provided recording sheet. Answers can be checked using the answer key that matches the student recording sheet.

This resource is an engaging way to practice calculating 10 or 100 more or less than a given number up to 1,200.

Tips for Differentiation + Scaffolding 

A team of dedicated, experienced educators created this resource to support your maths lessons.

If you have a mixture of above and below-level learners, check out these suggestions for keeping students on track with the concepts: 

🆘 Support Struggling Students

To provide additional support, use physical manipulatives or a hundreds chart. Reiterate the patterns in place value that are demonstrated as we add or subtract 10 or 100 from a given number.

➕ Challenge Fast Finishers

As an extension, ask students to create phrases that explain the relationship between the number on each card and the incorrect choices on each card. For example, on Card 1, an incorrect choice is 264, so a student might say ‘10 more than 254.’

🛴 Scoot Activity 

Place the cards around the room in numerical order and give each student a recording sheet. Assign students or pairs to a starting point card. Give students time to review the card and record their answers in the corresponding space on their paper. Students will rotate to the next card when you say, ‘SCOOT!’ Continue in this manner until students return to their starting point. 

👋 Exit Ticket 

Use these cards as a formative assessment after your lesson. Pick a random assortment of cards and project them on the board for the whole class to see. Students can record their answers on a sheet of paper, sticky note or their notebook.
