Take a 10 by 10 square grid and write a set of 100 numbers, such as 1 to 100,

101 to 200 or 201 to 300, on it. Then, take a number window and place it on
the number chart as shown below.

101 102 103 104 105 106 107 108 109 110

111 112 113 114 115 116 less 120

121 122 123 124 125 126 less 128 more 130

131 132 133 134 135 136 more 140

141 142 143 144 145 146 147 148 149 150

151 152 153 154 155 156 157 158 159 160

161 162 163 164 165 166 167 168 169 170

171 172 173 174 175 176 177 178 179 180

181 182 183 184 185 186 187 188 189 190

191 192 193 194 195 196 197 198 199 200

Now, ask your friends some questions. For example:

1. If the centre of the window is placed on 128, which
number will be above it?

2. Which number will be below it?

3. Which number will be on its right?

4. Which number will be on its left?
