Enchanted Forest/Woods inspired Maths Lesson One More/One Less/Ten More/Ten Less

This is an extremely detailed lesson plan used for a Maths observation. Our topic was The Enchanted Wood, and I like to try and link my lessons to the topic. Most resources are included or should be available in most classrooms. However, I did make the large 100 square for the floor with the children earlier in the week. They each decorated some number squares with woodland creatures, trees, flowers etc for our 'Out of the Woods' game, and then we 'tacky backed' it together. Good for number recognition/ordering. The frog game is available on Twinkl, or you could easily make some frog counters and lily pads. Resources included are the learning objectives, success criteria and plenary reflection questions. Also, word problems for the whole class and guided activity, along with true/false cards. The lesson is clearly differentiated for children still working on one more/one less to 20, one more/one less to 100, ten more/ten less, and application of this knowledge to solving word problems. Extension ideas are also included.
This lesson was planned for a Year 1 class and enjoyed by all.
